+//
+// The format of the file is rather simple: A section starts with three
+// labels separated by whitespace and followed by a colon (everything in a
+// single line); the first label gives the name of the enumeration template,
+// the second the name of the array template, and the third the name of the
+// `maximum' template. The script then fills the corresponding templates
+// (indicated by `@' characters around the name).
+//
+// A section contains one or more data records. Each data record consists
+// of two or more lines. The first line holds the enumeration name, and the
+// remaining lines the corresponding array data.
+//
+// There are two possible representations for array data.
+//
+// - A string of characters or character clusters (for example, representing
+// Aksharas, Devanagari syllables) in UTF-8 encoding enclosed in double
+// quotes, using C syntax, where the elements are separated by spaces.
+// There can be only one string per line, thus the starting and ending
+// double quote must be the first and last character in the line,
+// respectively, ignoring whitespace before and after the string. If
+// there are multiple strings (in multiple lines), they are concatenated
+// to a single string. In the output, a string gets represented as a
+// series of singles bytes, followed by a zero byte. The enumeration
+// values simply hold byte offsets to the start of the corresponding
+// strings.
+//
+// For strings, the `maximum' template holds the maximum number of
+// non-space characters in all strings.
+//
+// - Data blocks enclosed in balanced braces, which get copied verbatim and
+// which can span multiple lines. The opening brace of a block must be
+// the first character of a line (ignoring whitespace), and the closing
+// brace the last (ignoring whitespace also). The script appends a comma
+// character after each block and counts the number of blocks to set the
+// enumeration values.
+//
+// For data blocks, the `maximum' template holds the maximum number of
+// array elements.
+//
+// A section can contain either strings only or data blocks only.
+//
+// A comment line starts with `//'; it gets removed. A preprocessor
+// directive line (using the standard syntax of `cpp') starts with `#' and
+// gets copied verbatim to both the enumeration and the array. Whitespace
+// outside of a string is insignificant.
+//
+// Preprocessor directives are ignored while the script computes maximum
+// values; this essentially means that the maximum values can easily be too
+// large. Given that the purpose of those values is to create local
+// fixed-size arrays at compile time for further processing of the blue zone
+// data, this isn't a problem. Note the final zero byte of a string is not
+// counted. Note also that the count holds the number of UTF-8 encoded
+// characters, not bytes.
+
+
+// The blue zone string data, to be used in the blue stringsets below.

+// The blue zone stringsets, as used in the script styles, cf. `afstyles.h'.
+//
+// The AF_BLUE_PROPERTY_XXX flags are defined in `afblue.h'; here some
+// explanations.
+//
+// A blue zone in general is defined by a reference and an overshoot line.
+// During the hinting process, all coordinate values between those two lines
+// are set equal to the reference value, provided that the blue zone is not
+// wider than 0.75 pixels (otherwise the blue zone gets ignored). All
+// entries must have `AF_BLUE_STRING_MAX' as the final line.
+//
+// During the glyph analysis, edges are sorted from bottom to top, and then
+// sequentially checked, edge by edge, against the blue zones in the order
+// given below.
+//
+//
+// latin auto-hinter
+// -----------------
+//
+// Characters in a blue string are automatically classified as having a flat
+// (reference) or a round (overshoot) extremum. The blue zone is then set
+// up by the mean values of all flat extrema and all round extrema,
+// respectively. Only horizontal blue zones (i.e., adjusting vertical
+// coordinate values) are supported.
+//
+// Some scripts like Khmer need character composition to get all necessary
+// blue zones, since Unicode only provides an abstract data model that
+// doesn't represent all possible glyph shapes. For such character
+// clusters, the HarfBuzz library is used to convert them into the
+// corresponding glyphs. The largest glyph element (where `largest' can be
+// either `largest ascender' or `largest descender') then defines the
+// corresponding flat or round extremum.
+//
+// For the latin auto-hinter, the overshoot should be larger than the
+// reference for top zones, and vice versa for bottom zones.
+//
+// LATIN_TOP
+// Take the maximum flat and round coordinate values of the blue string
+// characters for computing the blue zone's reference and overshoot
+// values.
+//
+// If not set, take the minimum values.
+//
+// Mutually exclusive with `LATIN_SUB_TOP'.
+//
+// LATIN_SUB_TOP
+// For all glyphs of a character cluster, compute the maximum flat
+// and round coordinate values of each component, then take the
+// smallest of the maximum values. The idea is to get the top of
+// subscript glyphs, as used in Khmer, for example. Note that
+// this mechanism doesn't work for ordinary ligatures.
+//
+// This flags indicates a secondary blue zone: It gets removed if
+// there is a non-LATIN_SUB_TOP blue zone at the same coordinate
+// value (after scaling).
+//
+// Mutually exclusive with `LATIN_TOP'.
+//
+// LATIN_NEUTRAL
+// Ignore round extrema and define the blue zone with flat values only.
+// Both top and bottom of contours can match. This is useful for
+// scripts like Devanagari where vowel signs attach to the base
+// character and are implemented as components of composite glyphs.
+//
+// If not set, both round and flat extrema are taken into account.
+// Additionally, only the top or the bottom of a contour can match,
+// depending on the LATIN_TOP flag.
+//
+// Neutral blue zones should always follow non-neutral blue zones.
+//
+// LATIN_X_HEIGHT
+// Scale all glyphs vertically from the corresponding script to make the
+// reference line of this blue zone align on the grid. The scaling
+// takes place before all other blue zones get aligned to the grid.
+// Only one blue character string of a script style can have this flag.
+//
+// LATIN_LONG
+// Apply an additional constraint for blue zone values: Don't
+// necessarily use the extremum as-is but a segment of the topmost (or
+// bottommost) contour that is longer than a heuristic threshold, and
+// which is not too far away vertically from the real extremum. This
+// ensures that small bumps in the outline are ignored (for example, the
+// `vertical serifs' found in many Hebrew glyph designs).
+//
+// The segment must be at least EM/25 font units long, and the distance
+// to the extremum must be smaller than EM/4.
+//
+//
+// cjk auto-hinter
+// ---------------
+//
+// Characters in a blue string are *not* automatically classified. Instead,
+// first come the characters used for the overshoot value, then the
+// character `|', then the characters used for the reference value
+// (everything separated by space characters). The blue zone is then set up
+// by the mean values of all reference values and all overshoot values,
+// respectively. Both horizontal and vertical blue zones (i.e., adjusting
+// vertical and horizontal coordinate values, respectively) are supported.
+//
+// For the cjk auto-hinter, the overshoot should be smaller than the
+// reference for top zones, and vice versa for bottom zones.
+//
+// CJK_TOP
+// Take the maximum flat and round coordinate values of the blue string
+// characters. If not set, take the minimum values.
+//
+// CJK_RIGHT
+// A synonym for CJK_TOP. If CJK_HORIZ is set, this flag indicates the
+// right blue zone, taking horizontal maximum values.
+//
+// CJK_HORIZ
+// Define a blue zone for horizontal hinting (i.e., vertical blue
+// zones). If not set, this is a blue zone for vertical hinting.

+ * The following explanations are mostly taken from the article

+ *
+ *
+ * Segments
+ *
+ * `af_{cjk,latin,...}_hints_compute_segments' are the functions to
+ * find segments in an outline.
+ *
+ * A segment is a series of at least two consecutive points that are
+ * approximately aligned along a coordinate axis. The analysis to do
+ * so is specific to a writing system.
+ *
+ *
+ * Edges
+ *
+ * `af_{cjk,latin,...}_hints_compute_edges' are the functions to find
+ * edges.
+ *
+ * As soon as segments are defined, the auto-hinter groups them into
+ * edges. An edge corresponds to a single position on the main
+ * dimension that collects one or more segments (allowing for a small
+ * threshold).
+ *
+ * As an example, the `latin' writing system first tries to grid-fit
+ * edges, then to align segments on the edges unless it detects that
+ * they form a serif.

+ * D E
+ *
+ *
+ * Stems
+ *
+ * Stems are detected by `af_{cjk,latin,...}_hint_edges'.
+ *
+ * Segments need to be `linked' to other ones in order to detect stems.
+ * A stem is made of two segments that face each other in opposite
+ * directions and that are sufficiently close to each other. Using
+ * vocabulary from the TrueType specification, stem segments form a
+ * `black distance'.
+ *
+ * In the above ASCII drawing, the horizontal segments are BC, DE, and
+ * FG; the vertical segments are AB, CD, EF, and GH.
+ *
+ * Each segment has at most one `best' candidate to form a black
+ * distance, or no candidate at all. Notice that two distinct segments
+ * can have the same candidate, which frequently means a serif.
+ *
+ * A stem is recognized by the following condition:
+ *
+ * best segment_1 = segment_2 && best segment_2 = segment_1
+ *
+ * The best candidate is stored in field `link' in structure
+ * `AF_Segment'.
+ *
+ * In the above ASCII drawing, the best candidate for both AB and CD is
+ * GH, while the best candidate for GH is AB. Similarly, the best
+ * candidate for EF and GH is AB, while the best candidate for AB is
+ * GH.
+ *
+ * The detection and handling of stems is dependent on the writing
+ * system.
+ *
+ *
+ * Serifs
+ *
+ * Serifs are detected by `af_{cjk,latin,...}_hint_edges'.
+ *
+ * In comparison to a stem, a serif (as handled by the auto-hinter
+ * module that takes care of the `latin' writing system) has
+ *
+ * best segment_1 = segment_2 && best segment_2 != segment_1
+ *
+ * where segment_1 corresponds to the serif segment (CD and EF in the
+ * above ASCII drawing).
+ *
+ * The best candidate is stored in field `serif' in structure
+ * `AF_Segment' (and `link' is set to NULL).
+ *
+ *
+ * Touched points
+ *
+ * A point is called `touched' if it has been processed somehow by the
+ * auto-hinter. It basically means that it shouldn't be moved again
+ * (or moved only under certain constraints to preserve the already
+ * applied processing).
+ *
+ *
+ * Flat and round segments
+ *
+ * Segments are `round' or `flat', depending on the series of points
+ * that define them. A segment is round if the next and previous point
+ * of an extremum (which can be either a single point or sequence of
+ * points) are both conic or cubic control points. Otherwise, a
+ * segment with an extremum is flat.
+ *
+ *
+ * Strong Points
+ *
+ * Experience has shown that points not part of an edge need to be
+ * interpolated linearly between their two closest edges, even if these
+ * are not part of the contour of those particular points. Typical
+ * candidates for this are
+ *
+ * - angle points (i.e., points where the `in' and `out' direction
+ * differ greatly)
+ *
+ * - inflection points (i.e., where the `in' and `out' angles are the
+ * same, but the curvature changes sign) [currently, such points
+ * aren't handled specially in the auto-hinter]
+ *
+ * `af_glyph_hints_align_strong_points' is the function that takes
+ * care of such situations; it is equivalent to the TrueType `IP'
+ * hinting instruction.
+ *
+ *
+ * Weak Points
+ *
+ * Other points in the outline must be interpolated using the
+ * coordinates of their previous and next unfitted contour neighbours.
+ * These are called `weak points' and are touched by the function
+ * `af_glyph_hints_align_weak_points', equivalent to the TrueType `IUP'
+ * hinting instruction. Typical candidates are control points and
+ * points on the contour without a major direction.
+ *
+ * The major effect is to reduce possible distortion caused by
+ * alignment of edges and strong points, thus weak points are processed
+ * after strong points.

+ * Various OpenType features might use the same glyphs at different
+ * vertical positions; for example, superscript and subscript glyphs
+ * could be the same. However, the auto-hinter is completely
+ * agnostic of OpenType features after the feature analysis has been
+ * completed: The engine then simply receives a glyph index and returns a
+ * hinted and usually rendered glyph.
+ *
+ * Consider the superscript feature of font `pala.ttf': Some of the
+ * glyphs are `real', this is, they have a zero vertical offset, but
+ * most of them are small caps glyphs shifted up to the superscript
+ * position (this is, the `sups' feature is present in both the GSUB and
+ * GPOS tables). The code for blue zones computation actually uses a
+ * feature's y offset so that the `real' glyphs get correct hints. But
+ * later on it is impossible to decide whether a glyph index belongs to,
+ * say, the small caps or superscript feature.
+ *
+ * For this reason, we don't assign a style to a glyph if the current
+ * feature covers the glyph in both the GSUB and the GPOS tables. This
+ * is quite a broad condition, assuming that
+ *
+ * (a) glyphs that get used in multiple features are present in a
+ * feature without vertical shift,
+ *
+ * and
+ *
+ * (b) a feature's GPOS data really moves the glyph vertically.
+ *
+ * Not fulfilling condition (a) makes a font larger; it would also
+ * reduce the number of glyphs that could be addressed directly without
+ * using OpenType features, so this assumption is rather strong.
+ *
+ * Condition (b) is much weaker, and there might be glyphs which get
+ * missed. However, the OpenType features we are going to handle are
+ * primarily located in GSUB, and HarfBuzz doesn't provide an API to
+ * directly get the necessary information from the GPOS table. A
+ * possible solution might be to directly parse the GPOS table to find
+ * out whether a glyph gets shifted vertically, but this is something I
+ * would like to avoid if not really necessary.
+ *
+ * Note that we don't follow this logic for the default coverage.
+ * Complex scripts like Devanagari have mandatory GPOS features to
+ * position many glyph elements, using mark-to-base or mark-to-ligature
+ * tables; the number of glyphs missed due to condition (b) would be far
+ * too large.

+ * Usually, a font contains more glyphs than can be addressed by its
+ * character map.
+ *
+ * In the PostScript font world, encoding vectors specific to a given
+ * task are used to select such glyphs, and these glyphs can be often
+ * recognized by having a suffix in its glyph names. For example, a
+ * superscript glyph `A' might be called `A.sup'. Unfortunately, this
+ * naming scheme is not standardized and thus unusable for us.
+ *
+ * In the OpenType world, a better solution was invented, namely
+ * `features', which cleanly separate a character's input encoding from
+ * the corresponding glyph's appearance, and which don't use glyph names
+ * at all. For our purposes, and slightly generalized, an OpenType
+ * feature is a name of a mapping that maps character codes to
+ * non-standard glyph indices (features get used for other things also).
+ * For example, the `sups' feature provides superscript glyphs, thus
+ * mapping character codes like `A' or `B' to superscript glyph
+ * representation forms. How this mapping happens is completely
+ * uninteresting to us.
+ *
+ * For the auto-hinter, a `coverage' represents all glyphs of an OpenType
+ * feature collected in a set (as listed below) that can be hinted
+ * together. To continue the above example, superscript glyphs must not
+ * be hinted together with normal glyphs because the blue zones
+ * completely differ.
+ *
+ * Note that FreeType itself doesn't compute coverages; it only provides
+ * the glyphs addressable by the default Unicode character map. Instead,
+ * we use the HarfBuzz library (if available), which has many functions
+ * exactly for this purpose.
+ *
+ * AF_COVERAGE_DEFAULT is special: It should cover everything that isn't
+ * listed separately (including the glyphs addressable by the character
+ * map). In case HarfBuzz isn't available, it exactly covers the glyphs
+ * addressable by the character map.

+ Notes
+
+ Mac suitcase files can (and often do!) contain multiple fonts. To
+ support this I use the face_index argument of FT_(Open|New)_Face()
+ functions, and pretend the suitcase file is a collection.
+
+ Warning: fbit and NFNT bitmap resources are not supported yet. In old
+ sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
+ resources instead of the `bdat' table in the sfnt resource. Therefore,
+ face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
+ resource is unavailable at present.
+
+ The Mac FOND support works roughly like this:
+
+ - Check whether the offered stream points to a Mac suitcase file. This
+ is done by checking the file type: it has to be 'FFIL' or 'tfil'. The
+ stream that gets passed to our init_face() routine is a stdio stream,
+ which isn't usable for us, since the FOND resources live in the
+ resource fork. So we just grab the stream->pathname field.
+
+ - Read the FOND resource into memory, then check whether there is a
+ TrueType font and/or(!) a Type 1 font available.
+
+ - If there is a Type 1 font available (as a separate `LWFN' file), read
+ its data into memory, massage it slightly so it becomes PFB data, wrap
+ it into a memory stream, load the Type 1 driver and delegate the rest
+ of the work to it by calling FT_Open_Face(). (XXX TODO: after this
+ has been done, the kerning data from the FOND resource should be
+ appended to the face: On the Mac there are usually no AFM files
+ available. However, this is tricky since we need to map Mac char
+ codes to ps glyph names to glyph ID's...)
+
+ - If there is a TrueType font (an `sfnt' resource), read it into memory,
+ wrap it into a memory stream, load the TrueType driver and delegate
+ the rest of the work to it, by calling FT_Open_Face().
+
+ - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
+ itself, even though it doesn't contains `POST' resources. To handle
+ this special case without opening the file an extra time, we just
+ ignore errors from the `LWFN' and fallback to the `sfnt' if both are
+ available.

+ FreeType font driver for BDF fonts
+
+ Francesco Zappa Nardelli
+ <francesco.zappa.nardelli@ens.fr>
+
+
+Introduction
+************
+
+BDF (Bitmap Distribution Format) is a bitmap font format defined by Adobe,
+which is intended to be easily understood by both humans and computers.
+This code implements a BDF driver for the FreeType library, following the
+Adobe Specification V 2.2. The specification of the BDF font format is
+available from Adobe's web site:
+
+ https://adobe-type-tools.github.io/font-tech-notes/pdfs/5005.BDF_Spec.pdf
+
+Many good bitmap fonts in bdf format come with XFree86 (www.XFree86.org).
+They do not define vertical metrics, because the X Consortium BDF
+specification has removed them.
+
+
+Encodings
+*********
+
+[This section is out of date, retained for historical reasons. BDF
+ properties can be retrieved with `FT_Get_BDF_Property`, character set ID
+ values with `FT_Get_BDF_Charset_ID`.]
+
+The variety of encodings that accompanies bdf fonts appears to encompass the
+small set defined in freetype.h. On the other hand, two properties that
+specify encoding and registry are usually defined in bdf fonts.
+
+I decided to make these two properties directly accessible, leaving to the
+client application the work of interpreting them. For instance:
+
+
+ #include FT_INTERNAL_BDF_TYPES_H
+
+ FT_Face face;
+ BDF_Public_Face bdfface;
+
+
+ FT_New_Face( library, ..., &face );
+
+ bdfface = (BDF_Public_Face)face;
+
+ if ( ( bdfface->charset_registry == "ISO10646" ) &&
+ ( bdfface->charset_encoding == "1" ) )
+ [..]
+
+
+Thus the driver always exports `ft_encoding_none' as face->charmap.encoding.
+FT_Get_Char_Index's behavior is unmodified, that is, it converts the ULong
+value given as argument into the corresponding glyph number.
+
+If the two properties are not available, Adobe Standard Encoding should be
+assumed.
+
+
+Anti-Aliased Bitmaps
+********************
+
+The driver supports an extension to the BDF format as used in Mark Leisher's
+xmbdfed bitmap font editor. Microsoft's SBIT tool expects bitmap fonts in
+that format for adding anti-aliased them to TrueType fonts. It introduces a
+fourth field to the `SIZE' keyword which gives the bpp value (bits per
+pixel) of the glyph data in the font. Possible values are 1 (the default),
+2 (four gray levels), 4 (16 gray levels), and 8 (256 gray levels). The
+driver returns either a bitmap with 1 bit per pixel or a pixmap with 8bits
+per pixel (using 4, 16, and 256 gray levels, respectively).
+
+
+Known problems
+**************
+
+- A font is entirely loaded into memory. Obviously, this is not the Right
+ Thing(TM). If you have big fonts I suggest you convert them into PCF
+ format (using the bdftopcf utility): the PCF font drive of FreeType can
+ perform incremental glyph loading.
+
+When I have some time, I will implement on-demand glyph parsing.
+
+- Except for encodings properties, client applications have no visibility of
+ the PCF_Face object. This means that applications cannot directly access
+ font tables and must trust FreeType.
+
+- Currently, glyph names are ignored.
+
+ I plan to give full visibility of the BDF_Face object in an upcoming
+ revision of the driver, thus implementing also glyph names.
+
+- As I have never seen a BDF font that defines vertical metrics, vertical
+ metrics are (parsed and) discarded. If you own a BDF font that defines
+ vertical metrics, please let me know (I will implement them in 5-10
+ minutes).

+ /*
+ *
+ * FTC_GCache is an _abstract_ cache object optimized to store glyph
+ * data. It works as follows:
+ *
+ * - It manages FTC_GNode objects. Each one of them can hold one or more
+ * glyph `items'. Item types are not specified in the FTC_GCache but
+ * in classes that extend it.
+ *
+ * - Glyph attributes, like face ID, character size, render mode, etc.,
+ * can be grouped into abstract `glyph families'. This avoids storing
+ * the attributes within the FTC_GCache, since it is likely that many
+ * FTC_GNodes will belong to the same family in typical uses.
+ *
+ * - Each FTC_GNode is thus an FTC_Node with two additional fields:
+ *
+ * * gindex: A glyph index, or the first index in a glyph range.
+ * * family: A pointer to a glyph `family'.
+ *
+ * - Family types are not fully specific in the FTC_Family type, but
+ * by classes that extend it.
+ *
+ * Note that both FTC_ImageCache and FTC_SBitCache extend FTC_GCache.
+ * They share an FTC_Family sub-class called FTC_BasicFamily which is
+ * used to store the following data: face ID, pixel/point sizes, load
+ * flags. For more details see the file `src/cache/ftcbasic.c'.
+ *
+ * Client applications can extend FTC_GNode with their own FTC_GNode
+ * and FTC_Family sub-classes to implement more complex caches (e.g.,
+ * handling automatic synthesis, like obliquing & emboldening, colored
+ * glyphs, etc.).
+ *
+ * See also the FTC_ICache & FTC_SCache classes in `ftcimage.h' and
+ * `ftcsbits.h', which both extend FTC_GCache with additional
+ * optimizations.
+ *
+ * A typical FTC_GCache implementation must provide at least the
+ * following:
+ *
+ * - FTC_GNode sub-class, e.g. MyNode, with relevant methods:
+ * my_node_new (must call FTC_GNode_Init)
+ * my_node_free (must call FTC_GNode_Done)
+ * my_node_compare (must call FTC_GNode_Compare)
+ * my_node_remove_faceid (must call ftc_gnode_unselect in case
+ * of match)
+ *
+ * - FTC_Family sub-class, e.g. MyFamily, with relevant methods:
+ * my_family_compare
+ * my_family_init
+ * my_family_reset (optional)
+ * my_family_done
+ *
+ * - FTC_GQuery sub-class, e.g. MyQuery, to hold cache-specific query
+ * data.
+ *
+ * - Constant structures for a FTC_GNodeClass.
+ *
+ * - MyCacheNew() can be implemented easily as a call to the convenience
+ * function FTC_GCache_New.
+ *
+ * - MyCacheLookup with a call to FTC_GCache_Lookup. This function will
+ * automatically:
+ *
+ * - Search for the corresponding family in the cache, or create
+ * a new one if necessary. Put it in FTC_GQUERY(myquery).family
+ *
+ * - Call FTC_Cache_Lookup.
+ *
+ * If it returns NULL, you should create a new node, then call
+ * ftc_cache_add as usual.

+ * callback. However, the manager maintains a small cache of FT_Face
+ * and FT_Size objects in order to speed up things considerably.
+ *
+ * - Manage one or more cache objects. Each cache is in charge of
+ * holding a varying number of `cache nodes'. Each cache node
+ * represents a minimal amount of individually accessible cached
+ * data. For example, a cache node can be an FT_Glyph image
+ * containing a vector outline, or some glyph metrics, or anything
+ * else.
+ *
+ * Each cache node has a certain size in bytes that is added to the
+ * total amount of `cache memory' within the manager.
+ *
+ * All cache nodes are located in a global LRU list, where the oldest
+ * node is at the tail of the list.
+ *
+ * Each node belongs to a single cache, and includes a reference
+ * count to avoid destroying it (due to caching).

+ * However, we need to `lock' the node before this operation to
+ * prevent it from being flushed within the loop.
+ *
+ * When we exit the loop, we unlock the node, then check the `error'
+ * variable. If it is non-zero, this means that the cache was
+ * completely flushed and that no usable memory was found to load
+ * the bitmap.
+ *
+ * We then prefer to return a value of 0 (i.e., NO MATCH). This
+ * ensures that the caller will try to allocate a new node.
+ * This operation consequently _fail_ and the lookup function
+ * returns the appropriate OOM error code.

+gxvalid: TrueType GX validator
+==============================
+
+
+1. What is this
+---------------
+
+ `gxvalid' is a module to validate TrueType GX tables: a collection of
+ additional tables in TrueType font which are used by `QuickDraw GX
+ Text', Apple Advanced Typography (AAT). In addition, gxvalid can
+ validates `kern' tables which have been extended for AAT. Like the
+ otvalid module, gxvalid uses FreeType 2's validator framework
+ (ftvalid).
+
+ You can link gxvalid with your program; before running your own layout
+ engine, gxvalid validates a font file. As the result, you can remove
+ error-checking code from the layout engine. It is also possible to
+ use gxvalid as a stand-alone font validator; the `ftvalid' test
+ program included in the ft2demo bundle calls gxvalid internally.
+ A stand-alone font validator may be useful for font developers.
+
+ This documents documents the following issues.
+
+ - supported TrueType GX tables
+ - fundamental validation limitations
+ - permissive error handling of broken GX tables
+ - `kern' table issue.
+
+
+2. Supported tables
+-------------------
+
+ The following GX tables are currently supported.
+
+ bsln
+ feat
+ just
+ kern(*)
+ lcar
+ mort
+ morx
+ opbd
+ prop
+ trak
+
+ The following GX tables are currently unsupported.
+
+ cvar
+ fdsc
+ fmtx
+ fvar
+ gvar
+ Zapf
+
+ The following GX tables won't be supported.
+
+ acnt(**)
+ hsty(***)
+
+ The following undocumented tables in TrueType fonts designed for Apple
+ platform aren't handled either.
+
+ addg
+ CVTM
+ TPNM
+ umif
+
+
+ *) The `kern' validator handles both the classic and the new kern
+ formats; the former is supported on both Microsoft and Apple
+ platforms, while the latter is supported on Apple platforms.
+
+ **) `acnt' tables are not supported by currently available Apple font
+ tools.
+
+ ***) There is one more Apple extension, `hsty', but it is for
+ Newton-OS, not GX (Newton-OS is a platform by Apple, but it can
+ use sfnt- housed bitmap fonts only). Therefore, it should be
+ excluded from `Apple platform' in the context of TrueType.
+ gxvalid ignores it as Apple font tools do so.
+
+
+ We have checked 183 fonts bundled with MacOS 9.1, MacOS 9.2, MacOS
+ 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. In addition,
+ we have checked 67 Dynalab fonts (designed for MacOS) and 189 Ricoh
+ fonts (designed for Windows and MacOS dual platforms). The number of
+ fonts including TrueType GX tables are as follows.
+
+ bsln: 76
+ feat: 191
+ just: 84
+ kern: 59
+ lcar: 4
+ mort: 326
+ morx: 19
+ opbd: 4
+ prop: 114
+ trak: 16
+
+ Dynalab and Ricoh fonts don't have GX tables except of `feat' and
+ `mort'.
+
+
+3. Fundamental validation limitations
+-------------------------------------
+
+ TrueType GX provides layout information to libraries for font
+ rasterizers and text layout. gxvalid can check whether the layout
+ data in a font is conformant to the TrueType GX format specified by
+ Apple. But gxvalid cannot check a how QuickDraw GX/AAT renderer uses
+ the stored information.
+
+ 3-1. Validation of State Machine activity
+ -----------------------------------------
+
+ QuickDraw GX/AAT uses a `State Machine' to provide `stateful' layout
+ features, and TrueType GX stores the state transition diagram of
+ this `State Machine' in a `StateTable' data structure. While the
+ State Machine receives a series of glyph IDs, the State Machine
+ starts with `start of text' state, walks around various states and
+ generates various layout information to the renderer, and finally
+ reaches the `end of text' state.
+
+ gxvalid can check essential errors like:
+
+ - possibility of state transitions to undefined states
+ - existence of glyph IDs that the State Machine doesn't know how
+ to handle
+ - the State Machine cannot compute the layout information from
+ given diagram
+
+ These errors can be checked within finite steps, and without the
+ State Machine itself, because these are `expression' errors of state
+ transition diagram.
+
+ There is no limitation about how long the State Machine walks
+ around, so validation of the algorithm in the state transition
+ diagram requires infinite steps, even if we had a State Machine in
+ gxvalid. Therefore, the following errors and problems cannot be
+ checked.
+
+ - existence of states which the State Machine never transits to
+ - the possibility that the State Machine never reaches `end of
+ text'
+ - the possibility of stack underflow/overflow in the State Machine
+ (in ligature and contextual glyph substitutions, the State
+ Machine can store 16 glyphs onto its stack)
+
+ In addition, gxvalid doesn't check `temporary glyph IDs' used in the
+ chained State Machines (in `mort' and `morx' tables). If a layout
+ feature is implemented by a single State Machine, a glyph ID
+ converted by the State Machine is passed to the glyph renderer, thus
+ it should not point to an undefined glyph ID. But if a layout
+ feature is implemented by chained State Machines, a component State
+ Machine (if it is not the final one) is permitted to generate
+ undefined glyph IDs for temporary use, because it is handled by next
+ component State Machine and not by the glyph renderer. To validate
+ such temporary glyph IDs, gxvalid must stack all undefined glyph IDs
+ which can occur in the output of the previous State Machine and
+ search them in the `ClassTable' structure of the current State
+ Machine. It is too complex to list all possible glyph IDs from the
+ StateTable, especially from a ligature substitution table.
+
+ 3-2. Validation of relationship between multiple layout features
+ ----------------------------------------------------------------
+
+ gxvalid does not validate the relationship between multiple layout
+ features at all.
+
+ If multiple layout features are defined in TrueType GX tables,
+ possible interactions, overrides, and conflicts between layout
+ features are implicitly given in the font too. For example, there
+ are several predefined spacing control features:
+
+ - Text Spacing (Proportional/Monospace/Half-width/Normal)
+ - Number Spacing (Monospaced-numbers/Proportional-numbers)
+ - Kana Spacing (Full-width/Proportional)
+ - Ideographic Spacing (Full-width/Proportional)
+ - CJK Roman Spacing (Half-width/Proportional/Default-roman
+ /Full-width-roman/Proportional)
+
+ If all layout features are independently managed, we can activate
+ inconsistent typographic rules like `Text Spacing=Monospace' and
+ `Ideographic Spacing=Proportional' at the same time.
+
+ The combinations of layout features is managed by a 32bit integer
+ (one bit each for selector setting), so we can define relationships
+ between up to 32 features, theoretically. But if one feature
+ setting affects another feature setting, we need typographic
+ priority rules to validate the relationship. Unfortunately, the
+ TrueType GX format specification does not give such information even
+ for predefined features.
+
+
+4. Permissive error handling of broken GX tables
+------------------------------------------------
+
+ When Apple's font rendering system finds an inconsistency, like a
+ specification violation or an unspecified value in a TrueType GX
+ table, it does not always return error. In most cases, the rendering
+ engine silently ignores such wrong values or even whole tables. In
+ fact, MacOS is shipped with fonts including broken GX/AAT tables, but
+ no harmful effects due to `officially broken' fonts are observed by
+ end-users.
+
+ gxvalid is designed to continue the validation process as long as
+ possible. When gxvalid find wrong values, gxvalid warns it at least,
+ and takes a fallback procedure if possible. The fallback procedure
+ depends on the debug level.
+
+ We used the following three tools to investigate Apple's error handling.
+
+ - FontValidator (for MacOS 8.5 - 9.2) resource fork font
+ - ftxvalidator (for MacOS X 10.1 -) dfont or naked-sfnt
+ - ftxdumperfuser (for MacOS X 10.1 -) dfont or naked-sfnt
+
+ However, all tests were done on a PowerPC based Macintosh; at present,
+ we have not checked those tools on a m68k-based Macintosh.
+
+ In total, we checked 183 fonts bundled to MacOS 9.1, MacOS 9.2, MacOS
+ 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. These fonts
+ are distributed officially, but many broken GX/AAT tables were found
+ by Apple's font tools. In the following, we list typical violation of
+ the GX specification, in fonts officially distributed with those Apple
+ systems.
+
+ 4-1. broken BinSrchHeader (19/183)
+ ----------------------------------
+
+ `BinSrchHeader' is a header of a data array for m68k platforms to
+ access memory efficiently. Although there are only two independent
+ parameters for real (`unitSize' and `nUnits'), BinSrchHeader has
+ three additional parameters which can be calculated from `unitSize'
+ and `nUnits', for fast setup. Apple font tools ignore them
+ silently, so gxvalid warns if it finds and inconsistency, and always
+ continues validation. The additional parameters are ignored
+ regardless of the consistency.
+
+ 19 fonts include such inconsistencies; all breaks are in the
+ BinSrchHeader structure of the `kern' table.
+
+ 4-2. too-short LookupTable (5/183)
+ ----------------------------------
+
+ LookupTable format 0 is a simple array to get a value from a given
+ GID (glyph ID); the index of this array is a GID too. Therefore,
+ the length of the array is expected to be same as the maximum GID
+ value defined in the `maxp' table, but there are some fonts whose
+ LookupTable format 0 is too short to cover all GIDs. FontValidator
+ ignores this error silently, ftxvalidator and ftxdumperfuser both
+ warn and continue. Similar problems are found in format 3 subtables
+ of `kern'. gxvalid warns always and abort if the validation level
+ is set to FT_VALIDATE_PARANOID.
+
+ 5 fonts include too-short kern format 0 subtables.
+ 1 font includes too-short kern format 3 subtable.
+
+ 4-3. broken LookupTable format 2 (1/183)
+ ----------------------------------------
+
+ LookupTable format 2, subformat 4 covers the GID space by a
+ collection of segments which are specified by `firstGlyph' and
+ `lastGlyph'. Some fonts store `firstGlyph' and `lastGlyph' in
+ reverse order, so the segment specification is broken. Apple font
+ tools ignore this error silently; a broken segment is ignored as if
+ it did not exist. gxvalid warns and normalize the segment at
+ FT_VALIDATE_DEFAULT, or ignore the segment at FT_VALIDATE_TIGHT, or
+ abort at FT_VALIDATE_PARANOID.
+
+ 1 font includes broken LookupTable format 2, in the `just' table.
+
+ *) It seems that all fonts manufactured by ITC for AppleWorks have
+ this error.
+
+ 4-4. bad bracketing in glyph property (14/183)
+ ----------------------------------------------
+
+ GX/AAT defines a `bracketing' property of the glyphs in the `prop'
+ table, to control layout features of strings enclosed inside and
+ outside of brackets. Some fonts give inappropriate bracket
+ properties to glyphs. Apple font tools warn about this error;
+ gxvalid warns too and aborts at FT_VALIDATE_PARANOID.
+
+ 14 fonts include wrong bracket properties.
+
+
+ 4-5. invalid feature number (117/183)
+ -------------------------------------
+
+ The GX/AAT extension can include 255 different layout features,
+ but popular layout features are predefined (see
+ https://developer.apple.com/fonts/TrueType-Reference-Manual/RM09/AppendixF.html).
+ Some fonts include feature numbers which are incompatible with the
+ predefined feature registry.
+
+ In our survey, there are 140 fonts including `feat' table.
+
+ a) 67 fonts use a feature number which should not be used.
+ b) 117 fonts set the wrong feature range (nSetting). This is mostly
+ found in the `mort' and `morx' tables.
+
+ Apple font tools give no warning, although they cannot recognize
+ what the feature is. At FT_VALIDATE_DEFAULT, gxvalid warns but
+ continues in both cases (a, b). At FT_VALIDATE_TIGHT, gxvalid warns
+ and aborts for (a), but continues for (b). At FT_VALIDATE_PARANOID,
+ gxvalid warns and aborts in both cases (a, b).
+
+ 4-6. invalid prop version (10/183)
+ ----------------------------------
+
+ As most TrueType GX tables, the `prop' table must start with a 32bit
+ version identifier: 0x00010000, 0x00020000 or 0x00030000. But some
+ fonts store nonsense binary data instead. When Apple font tools
+ find them, they abort the processing immediately, and the data which
+ follows is unhandled. gxvalid does the same.
+
+ 10 fonts include broken `prop' version.
+
+ All of these fonts are classic TrueType fonts for the Japanese
+ script, manufactured by Apple.
+
+ 4-7. unknown resource name (2/183)
+ ------------------------------------
+
+ NOTE: THIS IS NOT A TRUETYPE GX ERROR.
+
+ If a TrueType font is stored in the resource fork or in dfont
+ format, the data must be tagged as `sfnt' in the resource fork index
+ to invoke TrueType font handler for the data. But the TrueType font
+ data in `Keyboard.dfont' is tagged as `kbd', and that in
+ `LastResort.dfont' is tagged as `lst'. Apple font tools can detect
+ that the data is in TrueType format and successfully validate them.
+ Maybe this is possible because they are known to be dfont. The
+ current implementation of the resource fork driver of FreeType
+ cannot do that, thus gxvalid cannot validate them.
+
+ 2 fonts use an unknown tag for the TrueType font resource.
+
+5. `kern' table issues
+----------------------
+
+ In common terminology of TrueType, `kern' is classified as a basic and
+ platform-independent table. But there are Apple extensions of `kern',
+ and there is an extension which requires a GX state machine for
+ contextual kerning. Therefore, gxvalid includes a special validator
+ for `kern' tables. Unfortunately, there is no exact algorithm to
+ check Apple's extension, so gxvalid includes a heuristic algorithm to
+ find the proper validation routines for all possible data formats,
+ including the data format for Microsoft. By calling
+ classic_kern_validate() instead of gxv_validate(), you can specify the
+ `kern' format explicitly. However, current FreeType2 uses Microsoft
+ `kern' format only, others are ignored (and should be handled in a
+ library one level higher than FreeType).
+
+ 5-1. History
+ ------------
+
+ The original 16bit version of `kern' was designed by Apple in the
+ pre-GX era, and it was also approved by Microsoft. Afterwards,
+ Apple designed a new 32bit version of the `kern' table. According
+ to the documentation, the difference between the 16bit and 32bit
+ version is only the size of variables in the `kern' header. In the
+ following, we call the original 16bit version as `classic', and
+ 32bit version as `new'.
+
+ 5-2. Versions and dialects which should be differentiated
+ ---------------------------------------------------------
+
+ The `kern' table consists of a table header and several subtables.
+ The version number which identifies a `classic' or a `new' version
+ is explicitly written in the table header, but there are
+ undocumented differences between Microsoft's and Apple's formats.
+ It is called a `dialect' in the following. There are three cases
+ which should be handled: the new Apple-dialect, the classic
+ Apple-dialect, and the classic Microsoft-dialect. An analysis of
+ the formats and the auto detection algorithm of gxvalid is described
+ in the following.
+
+ 5-2-1. Version detection: classic and new kern
+ ----------------------------------------------
+
+ According to Apple TrueType specification, there are only two
+ differences between the classic and the new:
+
+ - The `kern' table header starts with the version number.
+ The classic version starts with 0x0000 (16bit),
+ the new version starts with 0x00010000 (32bit).
+
+ - In the `kern' table header, the number of subtables follows
+ the version number.
+ In the classic version, it is stored as a 16bit value.
+ In the new version, it is stored as a 32bit value.
+
+ From Apple font tool's output (DumpKERN is also tested in addition
+ to the three Apple font tools in above), there is another
+ undocumented difference. In the new version, the subtable header
+ includes a 16bit variable named `tupleIndex' which does not exist
+ in the classic version.
+
+ The new version can store all subtable formats (0, 1, 2, and 3),
+ but the Apple TrueType specification does not mention the subtable
+ formats available in the classic version.
+
+ 5-2-2. Available subtable formats in classic version
+ ----------------------------------------------------
+
+ Although the Apple TrueType specification recommends to use the
+ classic version in the case if the font is designed for both the
+ Apple and Microsoft platforms, it does not document the available
+ subtable formats in the classic version.
+
+ According to the Microsoft TrueType specification, the subtable
+ format assured for Windows and OS/2 support is only subtable
+ format 0. The Microsoft TrueType specification also describes
+ subtable format 2, but does not mention which platforms support
+ it. Subtable formats 1, 3, and higher are documented as reserved
+ for future use. Therefore, the classic version can store subtable
+ formats 0 and 2, at least. `ttfdump.exe', a font tool provided by
+ Microsoft, ignores the subtable format written in the subtable
+ header, and parses the table as if all subtables are in format 0.
+
+ `kern' subtable format 1 uses a StateTable, so it cannot be
+ utilized without a GX State Machine. Therefore, it is reasonable
+ to assume that format 1 (and 3) were introduced after Apple had
+ introduced GX and moved to the new 32bit version.
+
+ 5-2-3. Apple and Microsoft dialects
+ -----------------------------------
+
+ The `kern' subtable has a 16bit `coverage' field to describe
+ kerning attributes, but bit interpretations by Apple and Microsoft
+ are different: For example, Apple uses bits 0-7 to identify the
+ subtable, while Microsoft uses bits 8-15.
+
+ In addition, due to the output of DumpKERN and FontValidator,
+ Apple's bit interpretations of coverage in classic and new version
+ are incompatible also. In summary, there are three dialects:
+ classic Apple dialect, classic Microsoft dialect, and new Apple
+ dialect. The classic Microsoft dialect and the new Apple dialect
+ are documented by each vendors' TrueType font specification, but
+ the documentation for classic Apple dialect is not available.
+
+ For example, in the new Apple dialect, bit 15 is documented as
+ `set to 1 if the kerning is vertical'. On the other hand, in
+ classic Microsoft dialect, bit 1 is documented as `set to 1 if the
+ kerning is horizontal'. From the outputs of DumpKERN and
+ FontValidator, classic Apple dialect recognizes 15 as `set to 1
+ when the kerning is horizontal'. From the results of similar
+ experiments, classic Apple dialect seems to be the Endian reverse
+ of the classic Microsoft dialect.
+
+ As a conclusion it must be noted that no font tool can identify
+ classic Apple dialect or classic Microsoft dialect automatically.
+
+ 5-2-4. gxvalid auto dialect detection algorithm
+ -----------------------------------------------
+
+ The first 16 bits of the `kern' table are enough to identify the
+ version:
+
+ - if the first 16 bits are 0x0000, the `kern' table is in
+ classic Apple dialect or classic Microsoft dialect
+ - if the first 16 bits are 0x0001, and next 16 bits are 0x0000,
+ the kern table is in new Apple dialect.
+
+ If the `kern' table is a classic one, the 16bit `coverage' field
+ is checked next. Firstly, the coverage bits are decoded for the
+ classic Apple dialect using the following bit masks (this is based
+ on DumpKERN output):
+
+ 0x8000: 1=horizontal, 0=vertical
+ 0x4000: not used
+ 0x2000: 1=cross-stream, 0=normal
+ 0x1FF0: reserved
+ 0x000F: subtable format
+
+ If any of reserved bits are set or the subtable bits is
+ interpreted as format 1 or 3, we take it as `impossible in classic
+ Apple dialect' and retry, using the classic Microsoft dialect.
+
+ The most popular coverage in new Apple-dialect: 0x8000,
+ The most popular coverage in classic Apple-dialect: 0x0000,
+ The most popular coverage in classic Microsoft dialect: 0x0001.
+
+ 5-3. Tested fonts
+ -----------------
+
+ We checked 59 fonts bundled with MacOS and 38 fonts bundled with
+ Windows, where all font include a `kern' table.
+
+ - fonts bundled with MacOS
+ * new Apple dialect
+ format 0: 18
+ format 2: 1
+ format 3: 1
+ * classic Apple dialect
+ format 0: 14
+ * classic Microsoft dialect
+ format 0: 15
+
+ - fonts bundled with Windows
+ * classic Microsoft dialect
+ format 0: 38
+
+ It looks strange that classic Microsoft-dialect fonts are bundled to
+ MacOS: they come from MSIE for MacOS, except of MarkerFelt.dfont.
+
+
+ ACKNOWLEDGEMENT
+ ---------------
+
+ Some parts of gxvalid are derived from both the `gxlayout' module and
+ the `otvalid' module. Development of gxlayout was supported by the
+ Information-technology Promotion Agency(IPA), Japan.
+
+ The detailed analysis of undefined glyph ID utilization in `mort' and
+ `morx' tables is provided by George Williams.

+Name: zlib
+Short Name: zlib
+URL: http://zlib.net/
+Version: 1.2.12
+License: see `zlib.h`
+
+Description:
+"A massively spiffy yet delicately unobtrusive compression library."
+
+'zlib' is a free, general-purpose, legally unencumbered lossless
+data-compression library. 'zlib' implements the "deflate" compression
+algorithm described by RFC 1951, which combines the LZ77 (Lempel-Ziv)
+algorithm with Huffman coding. zlib also implements the zlib (RFC 1950) and
+gzip (RFC 1952) wrapper formats.
+
+Local Modifications:
+The files in this directory have been prepared as follows.
+
+ - Take the unmodified source code files from the zlib distribution that are
+ included by `ftgzip.c`.
+ - Copy `zconf.h` to `ftzconf.h` (which stays unmodified otherwise).
+ - Run zlib's `zlib2ansi` script on all `.c` files.
+ - Apply the diff file(s) in the `patches` folder.

+ A CRC of a message is computed on N braids of words in the message, where

+ running sparse CRCs are calculated respectively on each braid, at these
+ indices in the array of words: 0, 3, 6, ..., 1, 4, 7, ..., and 2, 5, 8, ...
+ This is done starting at a word boundary, and continues until as many blocks
+ of N * W bytes as are available have been processed. The results are combined
+ into a single CRC at the end. For this code, N must be in the range 1..6 and
+ W must be 4 or 8. The upper limit on N can be increased if desired by adding
+ more #if blocks, extending the patterns apparent in the code. In addition,
+ crc32.h would need to be regenerated, if the maximum N value is increased.
+
+ N and W are chosen empirically by benchmarking the execution time on a given
+ processor. The choices for N and W below were based on testing on Intel Kaby
+ Lake i7, AMD Ryzen 7, ARM Cortex-A57, Sparc64-VII, PowerPC POWER9, and MIPS64
+ Octeon II processors. The Intel, AMD, and ARM processors were all fastest
+ with N=5, W=8. The Sparc, PowerPC, and MIPS64 were all fastest at N=5, W=4.

+
+ Polynomials over GF(2) are represented in binary, one bit per coefficient,

+ where a mod b means the remainder after dividing a by b.
+
+ This calculation is done using the shift-register method of multiplying and
+ taking the remainder. The register is initialized to zero, and for each
+ incoming bit, x^32 is added mod p to the register if the bit is a one (where
+ x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by x
+ (which is shifting right by one and adding x^32 mod p if the bit shifted out
+ is a one). We start with the highest power (least significant bit) of q and
+ repeat for all eight bits of q.
+
+ The table is simply the CRC of all possible eight bit values. This is all the
+ information needed to generate CRCs on data a byte at a time for all

+ inflateBack() needs more input, it calls in(). When inflateBack() has
+ filled the window with output, or when it completes with data in the

+
+ in() and out() are called with a descriptor parameter provided in the

+ information required to do the read or write, as well as accumulated
+ information on the input and output such as totals and check values.
+
+ in() should return zero on failure. out() should return non-zero on
+ failure. If either in() or out() fails, than inflateBack() returns a
+ Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
+ was in() or out() that caused in the error. Otherwise, inflateBack()
+ returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format

+ Decode literal, length, and distance codes and write out the resulting
+ literal and match bytes until either not enough input or output is
+ available, an end-of-block is encountered, or a data error is encountered.
+ When large enough input and output buffers are supplied to inflate(), for
+ example, a 16K input buffer and a 64K output buffer, more than 95% of the
+ inflate execution time is spent in this routine.
+
+ Entry assumptions:
+
+ state->mode == LEN
+ strm->avail_in >= 6
+ strm->avail_out >= 258
+ start >= strm->avail_out
+ state->bits < 8
+
+ On return, state->mode is one of:
+
+ LEN -- ran out of enough output space or enough available input
+ TYPE -- reached end of block code, inflate() to interpret next block
+ BAD -- error in block data
+
+ Notes:
+
+ - The maximum input bits used by a length/distance pair is 15 bits for the
+ length code, 5 bits for the length extra, 15 bits for the distance code,
+ and 13 bits for the distance extra. This totals 48 bits, or six bytes.
+ Therefore if strm->avail_in >= 6, then there is enough input to avoid
+ checking for available input while decoding.
+
+ - The maximum bytes that a single length/distance pair can output is 258
+ bytes, which is the maximum length that can be coded. inflate_fast()
+ requires strm->avail_out >= 258 for each loop to avoid checking for
+ output space.

+/* inflate.c -- zlib decompression
+ * Copyright (C) 1995-2022 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ */
+
+/*
+ * Change history:
+ *
+ * 1.2.beta0 24 Nov 2002
+ * - First version -- complete rewrite of inflate to simplify code, avoid
+ * creation of window when not needed, minimize use of window when it is
+ * needed, make inffast.c even faster, implement gzip decoding, and to
+ * improve code readability and style over the previous zlib inflate code
+ *
+ * 1.2.beta1 25 Nov 2002
+ * - Use pointers for available input and output checking in inffast.c
+ * - Remove input and output counters in inffast.c
+ * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
+ * - Remove unnecessary second byte pull from length extra in inffast.c
+ * - Unroll direct copy to three copies per loop in inffast.c
+ *
+ * 1.2.beta2 4 Dec 2002
+ * - Change external routine names to reduce potential conflicts
+ * - Correct filename to inffixed.h for fixed tables in inflate.c
+ * - Make hbuf[] unsigned char to match parameter type in inflate.c
+ * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
+ * to avoid negation problem on Alphas (64 bit) in inflate.c
+ *
+ * 1.2.beta3 22 Dec 2002
+ * - Add comments on state->bits assertion in inffast.c
+ * - Add comments on op field in inftrees.h
+ * - Fix bug in reuse of allocated window after inflateReset()
+ * - Remove bit fields--back to byte structure for speed
+ * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
+ * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
+ * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
+ * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
+ * - Use local copies of stream next and avail values, as well as local bit
+ * buffer and bit count in inflate()--for speed when inflate_fast() not used
+ *
+ * 1.2.beta4 1 Jan 2003
+ * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
+ * - Move a comment on output buffer sizes from inffast.c to inflate.c
+ * - Add comments in inffast.c to introduce the inflate_fast() routine
+ * - Rearrange window copies in inflate_fast() for speed and simplification
+ * - Unroll last copy for window match in inflate_fast()
+ * - Use local copies of window variables in inflate_fast() for speed
+ * - Pull out common wnext == 0 case for speed in inflate_fast()
+ * - Make op and len in inflate_fast() unsigned for consistency
+ * - Add FAR to lcode and dcode declarations in inflate_fast()
+ * - Simplified bad distance check in inflate_fast()
+ * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
+ * source file infback.c to provide a call-back interface to inflate for
+ * programs like gzip and unzip -- uses window as output buffer to avoid
+ * window copying
+ *
+ * 1.2.beta5 1 Jan 2003
+ * - Improved inflateBack() interface to allow the caller to provide initial
+ * input in strm.
+ * - Fixed stored blocks bug in inflateBack()
+ *
+ * 1.2.beta6 4 Jan 2003
+ * - Added comments in inffast.c on effectiveness of POSTINC
+ * - Typecasting all around to reduce compiler warnings
+ * - Changed loops from while (1) or do {} while (1) to for (;;), again to
+ * make compilers happy
+ * - Changed type of window in inflateBackInit() to unsigned char *
+ *
+ * 1.2.beta7 27 Jan 2003
+ * - Changed many types to unsigned or unsigned short to avoid warnings
+ * - Added inflateCopy() function
+ *
+ * 1.2.0 9 Mar 2003
+ * - Changed inflateBack() interface to provide separate opaque descriptors
+ * for the in() and out() functions
+ * - Changed inflateBack() argument and in_func typedef to swap the length
+ * and buffer address return values for the input function
+ * - Check next_in and next_out for Z_NULL on entry to inflate()
+ *
+ * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

+ inflate() uses a state machine to process as much input data and generate as
+ much output data as possible before returning. The state machine is
+ structured roughly as follows:
+
+ for (;;) switch (state) {
+ ...
+ case STATEn:
+ if (not enough input data or output space to make progress)
+ return;
+ ... make progress ...
+ state = STATEm;
+ break;
+ ...
+ }
+
+ so when inflate() is called again, the same case is attempted again, and
+ if the appropriate resources are provided, the machine proceeds to the
+ next state. The NEEDBITS() macro is usually the way the state evaluates
+ whether it can proceed or should return. NEEDBITS() does the return if
+ the requested bits are not available. The typical use of the BITS macros
+ is:
+
+ NEEDBITS(n);
+ ... do something with BITS(n) ...
+ DROPBITS(n);
+
+ where NEEDBITS(n) either returns from inflate() if there isn't enough
+ input left to load n bits into the accumulator, or it continues. BITS(n)
+ gives the low n bits in the accumulator. When done, DROPBITS(n) drops
+ the low n bits off the accumulator. INITBITS() clears the accumulator
+ and sets the number of available bits to zero. BYTEBITS() discards just
+ enough bits to put the accumulator on a byte boundary. After BYTEBITS()
+ and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+ NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+ if there is no input available. The decoding of variable length codes uses
+ PULLBYTE() directly in order to pull just enough bytes to decode the next
+ code, and no more.
+
+ Some states loop until they get enough input, making sure that enough
+ state information is maintained to continue the loop where it left off
+ if NEEDBITS() returns in the loop. For example, want, need, and keep
+ would all have to actually be part of the saved state in case NEEDBITS()
+ returns:
+
+ case STATEw:
+ while (want < need) {
+ NEEDBITS(n);
+ keep[want++] = BITS(n);
+ DROPBITS(n);
+ }
+ state = STATEx;
+ case STATEx:
+
+ As shown above, if the next state is also the next case, then the break
+ is omitted.
+
+ A state may also return if there is not enough output space available to
+ complete that state. Those states are copying stored data, writing a
+ literal byte, and copying a matching string.
+
+ When returning, a "goto inf_leave" is used to update the total counters,
+ update the check value, and determine whether any progress has been made
+ during that inflate() call in order to return the proper return code.
+ Progress is defined as a change in either strm->avail_in or strm->avail_out.
+ When there is a window, goto inf_leave will update the window with the last
+ output written. If a goto inf_leave occurs in the middle of decompression
+ and there is no window currently, goto inf_leave will create one and copy
+ output to the window for the next call of inflate().
+
+ In this implementation, the flush parameter of inflate() only affects the
+ return code (per zlib.h). inflate() always writes as much as possible to
+ strm->next_out, given the space available and the provided input--the effect
+ documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers
+ the allocation of and copying into a sliding window until necessary, which
+ provides the effect documented in zlib.h for Z_FINISH when the entire input
+ stream available. So the only thing the flush parameter actually does is:
+ when flush is set to Z_FINISH, inflate() cannot return Z_OK. Instead it
+ will return Z_BUF_ERROR if it has not reached the end of the stream.

+ The 'zlib' compression library provides in-memory compression and
+ decompression functions, including integrity checks of the uncompressed data.
+ This version of the library supports only one compression method (deflation)
+ but other algorithms will be added later and will have the same stream
+ interface.
+
+ Compression can be done in a single step if the buffers are large enough,
+ or can be done by repeated calls of the compression function. In the latter
+ case, the application must provide more input and/or consume the output
+ (providing more output space) before each call.
+
+ The compressed data format used by default by the in-memory functions is
+ the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+ around a deflate stream, which is itself documented in RFC 1951.
+
+ The library also supports reading and writing files in gzip (.gz) format
+ with an interface similar to that of stdio using the functions that start
+ with "gz". The gzip format is different from the zlib format. gzip is a
+ gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+ This library can optionally read and write gzip and raw deflate streams in
+ memory as well.
+
+ The zlib format was designed to be compact and fast for use in memory
+ and on communications channels. The gzip format was designed for single-
+ file compression on file systems, has a larger header than zlib to maintain
+ directory information, and uses a different, slower check method than zlib.
+
+ The library does not install any signal handler. The decoder checks
+ the consistency of the compressed data, so the library should never crash
+ even in the case of corrupted input.

+ The application must update next_in and avail_in when avail_in has dropped

+ to zero. The application must initialize zalloc, zfree and opaque before
+ calling the init function. All other fields are set by the compression
+ library and must not be updated by the application.
+
+ The opaque value provided by the application will be passed as the first
+ parameter for calls of zalloc and zfree. This can be useful for custom
+ memory management. The compression library attaches no meaning to the
+ opaque value.
+
+ zalloc must return Z_NULL if there is not enough memory for the object.
+ If zlib is used in a multi-threaded application, zalloc and zfree must be
+ thread safe. In that case, zlib is thread-safe. When zalloc and zfree are
+ Z_NULL on entry to the initialization function, they are set to internal
+ routines that use the standard library functions malloc() and free().
+
+ On 16-bit systems, the functions zalloc and zfree must be able to allocate
+ exactly 65536 bytes, but will not be required to allocate more than this if
+ the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS, pointers
+ returned by zalloc for objects of exactly 65536 bytes *must* have their
+ offset normalized to zero. The default allocation function provided by this
+ library ensures this (see zutil.c). To reduce memory requirements and avoid
+ any allocation of 64K objects, at the expense of compression ratio, compile
+ the library with -DMAX_WBITS=14 (see zconf.h).
+
+ The fields total_in and total_out can be used for statistics or progress
+ reports. After compression, total_in holds the total size of the
+ uncompressed data and may be saved for use by the decompressor (particularly
+ if the decompressor wants to decompress everything in a single step).

+/*
+ deflate compresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. deflate performs one or both of the
+ following actions:
+
+ - Compress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in and avail_in are updated and
+ processing will resume at this point for the next call of deflate().
+
+ - Generate more output starting at next_out and update next_out and avail_out
+ accordingly. This action is forced if the parameter flush is non zero.
+ Forcing flush frequently degrades the compression ratio, so this parameter
+ should be set only when necessary. Some output may be provided even if
+ flush is zero.
+
+ Before the call of deflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming more
+ output, and updating avail_in or avail_out accordingly; avail_out should
+ never be zero before the call. The application can consume the compressed
+ output when it wants, for example when the output buffer is full (avail_out
+ == 0), or after each call of deflate(). If deflate returns Z_OK and with
+ zero avail_out, it must be called again after making room in the output
+ buffer because there might be more output pending. See deflatePending(),
+ which can be used if desired to determine whether or not there is more output
+ in that case.
+
+ Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+ decide how much data to accumulate before producing output, in order to
+ maximize compression.
+
+ If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+ flushed to the output buffer and the output is aligned on a byte boundary, so
+ that the decompressor can get all input data available so far. (In
+ particular avail_in is zero after the call if enough output space has been
+ provided before the call.) Flushing may degrade compression for some
+ compression algorithms and so it should be used only when necessary. This
+ completes the current deflate block and follows it with an empty stored block
+ that is three bits plus filler bits to the next byte, followed by four bytes
+ (00 00 ff ff).
+
+ If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+ output buffer, but the output is not aligned to a byte boundary. All of the
+ input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+ This completes the current deflate block and follows it with an empty fixed
+ codes block that is 10 bits long. This assures that enough bytes are output
+ in order for the decompressor to finish the block before the empty fixed
+ codes block.
+
+ If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+ for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+ seven bits of the current block are held to be written as the next byte after
+ the next deflate block is completed. In this case, the decompressor may not
+ be provided enough bits at this point in order to complete decompression of
+ the data provided so far to the compressor. It may need to wait for the next
+ block to be emitted. This is for advanced applications that need to control
+ the emission of deflate blocks.
+
+ If flush is set to Z_FULL_FLUSH, all output is flushed as with
+ Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+ restart from this point if previous compressed data has been damaged or if
+ random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+ compression.
+
+ If deflate returns with avail_out == 0, this function must be called again
+ with the same value of the flush parameter and more output space (updated
+ avail_out), until the flush is complete (deflate returns with non-zero
+ avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+ avail_out is greater than six to avoid repeated flush markers due to
+ avail_out == 0 on return.
+
+ If the parameter flush is set to Z_FINISH, pending input is processed,
+ pending output is flushed and deflate returns with Z_STREAM_END if there was
+ enough output space. If deflate returns with Z_OK or Z_BUF_ERROR, this
+ function must be called again with Z_FINISH and more output space (updated
+ avail_out) but no more input data, until it returns with Z_STREAM_END or an
+ error. After deflate has returned Z_STREAM_END, the only possible operations
+ on the stream are deflateReset or deflateEnd.
+
+ Z_FINISH can be used in the first deflate call after deflateInit if all the
+ compression is to be done in a single step. In order to complete in one
+ call, avail_out must be at least the value returned by deflateBound (see
+ below). Then deflate is guaranteed to return Z_STREAM_END. If not enough
+ output space is provided, deflate will not return Z_STREAM_END, and it must
+ be called again as described above.
+
+ deflate() sets strm->adler to the Adler-32 checksum of all input read
+ so far (that is, total_in bytes). If a gzip stream is being generated, then
+ strm->adler will be the CRC-32 checksum of the input read so far. (See
+ deflateInit2 below.)
+
+ deflate() may update strm->data_type if it can make a good guess about
+ the input data type (Z_BINARY or Z_TEXT). If in doubt, the data is
+ considered binary. This field is only for information purposes and does not
+ affect the compression algorithm in any manner.
+
+ deflate() returns Z_OK if some progress has been made (more input
+ processed or more output produced), Z_STREAM_END if all input has been
+ consumed and all output has been produced (only when flush is set to
+ Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+ if next_in or next_out was Z_NULL or the state was inadvertently written over
+ by the application), or Z_BUF_ERROR if no progress is possible (for example
+ avail_in or avail_out was zero). Note that Z_BUF_ERROR is not fatal, and

+ inflate decompresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. inflate performs one or both of the
+ following actions:
+
+ - Decompress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), then next_in and avail_in are updated
+ accordingly, and processing will resume at this point for the next call of
+ inflate().
+
+ - Generate more output starting at next_out and update next_out and avail_out
+ accordingly. inflate() provides as much output as possible, until there is
+ no more input data or no more space in the output buffer (see below about
+ the flush parameter).
+
+ Before the call of inflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming more
+ output, and updating the next_* and avail_* values accordingly. If the
+ caller of inflate() does not provide both available input and available
+ output space, it is possible that there will be no progress made. The
+ application can consume the uncompressed output when it wants, for example
+ when the output buffer is full (avail_out == 0), or after each call of
+ inflate(). If inflate returns Z_OK and with zero avail_out, it must be
+ called again after making room in the output buffer because there might be
+ more output pending.
+
+ The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+ Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much
+ output as possible to the output buffer. Z_BLOCK requests that inflate()
+ stop if and when it gets to the next deflate block boundary. When decoding
+ the zlib or gzip format, this will cause inflate() to return immediately
+ after the header and before the first block. When doing a raw inflate,
+ inflate() will go ahead and process the first block, and will return when it
+ gets to the end of that block, or when it runs out of data.
+
+ The Z_BLOCK option assists in appending to or combining deflate streams.
+ To assist in this, on return inflate() always sets strm->data_type to the
+ number of unused bits in the last byte taken from strm->next_in, plus 64 if
+ inflate() is currently decoding the last block in the deflate stream, plus
+ 128 if inflate() returned immediately after decoding an end-of-block code or
+ decoding the complete header up to just before the first byte of the deflate
+ stream. The end-of-block will not be indicated until all of the uncompressed
+ data from that block has been written to strm->next_out. The number of
+ unused bits may in general be greater than seven, except when bit 7 of
+ data_type is set, in which case the number of unused bits will be less than
+ eight. data_type is set as noted here every time inflate() returns for all
+ flush options, and so can be used to determine the amount of currently
+ consumed input in bits.
+
+ The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+ end of each deflate block header is reached, before any actual data in that
+ block is decoded. This allows the caller to determine the length of the
+ deflate block header for later use in random access within a deflate block.
+ 256 is added to the value of strm->data_type when inflate() returns
+ immediately after reaching the end of the deflate block header.
+
+ inflate() should normally be called until it returns Z_STREAM_END or an
+ error. However if all decompression is to be performed in a single step (a
+ single call of inflate), the parameter flush should be set to Z_FINISH. In
+ this case all pending input is processed and all pending output is flushed;
+ avail_out must be large enough to hold all of the uncompressed data for the
+ operation to complete. (The size of the uncompressed data may have been
+ saved by the compressor for this purpose.) The use of Z_FINISH is not
+ required to perform an inflation in one step. However it may be used to
+ inform inflate that a faster approach can be used for the single inflate()
+ call. Z_FINISH also informs inflate to not maintain a sliding window if the
+ stream completes, which reduces inflate's memory footprint. If the stream
+ does not complete, either because not all of the stream is provided or not
+ enough output space is provided, then a sliding window will be allocated and
+ inflate() can be called again to continue the operation as if Z_NO_FLUSH had
+ been used.
+
+ In this implementation, inflate() always flushes as much output as
+ possible to the output buffer, and always uses the faster approach on the
+ first call. So the effects of the flush parameter in this implementation are
+ on the return value of inflate() as noted below, when inflate() returns early
+ when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
+ memory for a sliding window when Z_FINISH is used.
+
+ If a preset dictionary is needed after this call (see inflateSetDictionary
+ below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
+ chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+ strm->adler to the Adler-32 checksum of all output produced so far (that is,
+ total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+ below. At the end of the stream, inflate() checks that its computed Adler-32
+ checksum is equal to that saved by the compressor and returns Z_STREAM_END
+ only if the checksum is correct.
+
+ inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+ deflate data. The header type is detected automatically, if requested when
+ initializing with inflateInit2(). Any information contained in the gzip
+ header is not retained unless inflateGetHeader() is used. When processing
+ gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
+ produced so far. The CRC-32 is checked against the gzip trailer, as is the
+ uncompressed length, modulo 2^32.
+
+ inflate() returns Z_OK if some progress has been made (more input processed

+
+ This is another version of deflateInit with more compression options. The
+ fields zalloc, zfree and opaque must be initialized before by the caller.
+
+ The method parameter is the compression method. It must be Z_DEFLATED in
+ this version of the library.
+
+ The windowBits parameter is the base two logarithm of the window size
+ (the size of the history buffer). It should be in the range 8..15 for this
+ version of the library. Larger values of this parameter result in better
+ compression at the expense of memory usage. The default value is 15 if
+ deflateInit is used instead.
+
+ For the current implementation of deflate(), a windowBits value of 8 (a
+ window size of 256 bytes) is not supported. As a result, a request for 8
+ will result in 9 (a 512-byte window). In that case, providing 8 to
+ inflateInit2() will result in an error when the zlib header with 9 is
+ checked against the initialization of inflate(). The remedy is to not use 8
+ with deflateInit2() with this initialization, or at least in that case use 9
+ with inflateInit2().
+
+ windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
+ determines the window size. deflate() will then generate raw deflate data
+ with no zlib header or trailer, and will not compute a check value.
+
+ windowBits can also be greater than 15 for optional gzip encoding. Add
+ 16 to windowBits to write a simple gzip header and trailer around the
+ compressed data instead of a zlib wrapper. The gzip header will have no
+ file name, no extra data, no comment, no modification time (set to zero), no
+ header crc, and the operating system will be set to the appropriate value,
+ if the operating system was determined at compile time. If a gzip stream is
+ being written, strm->adler is a CRC-32 instead of an Adler-32.
+
+ For raw deflate or gzip encoding, a request for a 256-byte window is
+ rejected as invalid, since only the zlib header provides a means of
+ transmitting the window size to the decompressor.
+
+ The memLevel parameter specifies how much memory should be allocated
+ for the internal compression state. memLevel=1 uses minimum memory but is
+ slow and reduces compression ratio; memLevel=9 uses maximum memory for
+ optimal speed. The default value is 8. See zconf.h for total memory usage
+ as a function of windowBits and memLevel.
+
+ The strategy parameter is used to tune the compression algorithm. Use the
+ value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+ filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+ string match), or Z_RLE to limit match distances to one (run-length
+ encoding). Filtered data consists mostly of small values with a somewhat
+ random distribution. In this case, the compression algorithm is tuned to
+ compress them better. The effect of Z_FILTERED is to force more Huffman
+ coding and less string matching; it is somewhat intermediate between
+ Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as
+ fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The
+ strategy parameter only affects the compression ratio but not the
+ correctness of the compressed output even if it is not set appropriately.
+ Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+ decoder for special applications.
+
+ deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+ memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
+ method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
+ incompatible with the version assumed by the caller (ZLIB_VERSION). msg is
+ set to null if there is no error message. deflateInit2 does not perform any
+ compression: this will be done by deflate().

+ function must be called either before any call of deflate, or immediately
+ after the completion of a deflate block, i.e. after all input has been
+ consumed and all output has been delivered when using any of the flush
+ options Z_BLOCK, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, or Z_FULL_FLUSH. The
+ compressor and decompressor must use exactly the same dictionary (see
+ inflateSetDictionary).
+
+ The dictionary should consist of strings (byte sequences) that are likely
+ to be encountered later in the data to be compressed, with the most commonly
+ used strings preferably put towards the end of the dictionary. Using a
+ dictionary is most useful when the data to be compressed is short and can be
+ predicted with good accuracy; the data can then be compressed better than
+ with the default empty dictionary.
+
+ Depending on the size of the compression data structures selected by
+ deflateInit or deflateInit2, a part of the dictionary may in effect be
+ discarded, for example if the dictionary is larger than the window size
+ provided in deflateInit or deflateInit2. Thus the strings most likely to be
+ useful should be put at the end of the dictionary, not at the front. In

+ size minus 262 bytes of the provided dictionary.

+ inflateBack() does a raw inflate with a single call using a call-back
+ interface for input and output. This is potentially more efficient than
+ inflate() for file i/o applications, in that it avoids copying between the
+ output and the sliding window by simply making the window itself the output
+ buffer. inflate() can be faster on modern CPUs when used with large
+ buffers. inflateBack() trusts the application to not change the output
+ buffer passed by the output function, at least until inflateBack() returns.
+
+ inflateBackInit() must be called first to allocate the internal state
+ and to initialize the state with the user-provided window buffer.
+ inflateBack() may then be used multiple times to inflate a complete, raw
+ deflate stream with each call. inflateBackEnd() is then called to free the
+ allocated state.
+
+ A raw deflate stream is one with no zlib or gzip header or trailer.
+ This routine would normally be used in a utility that reads zip or gzip
+ files and writes out uncompressed files. The utility would decode the
+ header and process the trailer on its own, hence this routine expects only
+ the raw deflate stream to decompress. This is different from the default
+ behavior of inflate(), which expects a zlib header and trailer around the
+ deflate stream.
+
+ inflateBack() uses two subroutines supplied by the caller that are then
+ called by inflateBack() for input and output. inflateBack() calls those
+ routines until it reads a complete deflate stream and writes out all of the
+ uncompressed data, or until it encounters an error. The function's
+ parameters and return types are defined above in the in_func and out_func
+ typedefs. inflateBack() will call in(in_desc, &buf) which should return the
+ number of bytes of provided input, and a pointer to that input in buf. If
+ there is no input available, in() must return zero -- buf is ignored in that
+ case -- and inflateBack() will return a buffer error. inflateBack() will
+ call out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].
+ out() should return zero on success, or non-zero on failure. If out()
+ returns non-zero, inflateBack() will return with an error. Neither in() nor
+ out() are permitted to change the contents of the window provided to
+ inflateBackInit(), which is also the buffer that out() uses to write from.
+ The length written by out() will be at most the window size. Any non-zero
+ amount of input may be provided by in().
+
+ For convenience, inflateBack() can be provided input on the first call by
+ setting strm->next_in and strm->avail_in. If that input is exhausted, then
+ in() will be called. Therefore strm->next_in must be initialized before
+ calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
+ immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
+ must also be initialized, and then if strm->avail_in is not zero, input will
+ initially be taken from strm->next_in[0 .. strm->avail_in - 1].
+
+ The in_desc and out_desc parameters of inflateBack() is passed as the
+ first parameter of in() and out() respectively when they are called. These
+ descriptors can be optionally used to pass any information that the caller-
+ supplied in() and out() functions need to do their job.
+
+ On return, inflateBack() will set strm->next_in and strm->avail_in to
+ pass back any unused input that was provided by the last in() call. The
+ return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+ if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+ in the deflate stream (in which case strm->msg is set to indicate the nature
+ of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+ In the case of Z_BUF_ERROR, an input or output error can be distinguished
+ using strm->next_in which will be Z_NULL only if in() returned an error. If
+ strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+ non-zero. (in() will always be called before out(), so strm->next_in is
+ assured to be defined if out() returns non-zero.) Note that inflateBack()
+ cannot return Z_OK.

+ *
+ * small technical note
+ * --------------------
+ *
+ * We use a few tricks in this implementation that are explained here to
+ * ease debugging and maintenance.
+ *
+ * - First of all, the `prefix' and `suffix' arrays contain the suffix
+ * and prefix for codes over 256; this means that
+ *
+ * prefix_of(code) == state->prefix[code-256]
+ * suffix_of(code) == state->suffix[code-256]
+ *
+ * Each prefix is a 16-bit code, and each suffix an 8-bit byte.
+ *
+ * Both arrays are stored in a single memory block, pointed to by
+ * `state->prefix'. This means that the following equality is always
+ * true:
+ *
+ * state->suffix == (FT_Byte*)(state->prefix + state->prefix_size)
+ *
+ * Of course, state->prefix_size is the number of prefix/suffix slots
+ * in the arrays, corresponding to codes 256..255+prefix_size.
+ *
+ * - `free_ent' is the index of the next free entry in the `prefix'
+ * and `suffix' arrays. This means that the corresponding `next free
+ * code' is really `256+free_ent'.
+ *
+ * Moreover, `max_free' is the maximum value that `free_ent' can reach.
+ *
+ * `max_free' corresponds to `(1 << max_bits) - 256'. Note that this
+ * value is always <= 0xFF00, which means that both `free_ent' and
+ * `max_free' can be stored in an FT_UInt variable, even on 16-bit
+ * machines.
+ *
+ * If `free_ent == max_free', you cannot add new codes to the
+ * prefix/suffix table.
+ *
+ * - `num_bits' is the current number of code bits, starting at 9 and
+ * growing each time `free_ent' reaches the value of `free_bits'. The
+ * latter is computed as follows
+ *
+ * if num_bits < max_bits:
+ * free_bits = (1 << num_bits)-256
+ * else:
+ * free_bits = max_free + 1
+ *
+ * Since the value of `max_free + 1' can never be reached by
+ * `free_ent', `num_bits' cannot grow larger than `max_bits'.

+ FreeType font driver for PCF fonts
+
+ Francesco Zappa Nardelli
+ <francesco.zappa.nardelli@ens.fr>
+
+
+Introduction
+************
+
+PCF (Portable Compiled Format) is a binary bitmap font format, largely used
+in X world. This code implements a PCF driver for the FreeType library.
+Glyph images are loaded into memory only on demand, thus leading to a small
+memory footprint.
+
+Information on the PCF font format can only be worked out from
+`pcfread.c', and `pcfwrite.c', to be found, for instance, in the XFree86
+(www.xfree86.org) source tree (xc/lib/font/bitmap/).
+
+Many good bitmap fonts in bdf format come with XFree86: they can be
+compiled into the pcf format using the `bdftopcf' utility.
+
+
+Supported hardware
+******************
+
+The driver has been tested on linux/x86 and sunos5.5/sparc. In both
+cases the compiler was gcc. When back in Paris, I will test it also
+on linux/alpha.
+
+
+Encodings
+*********
+
+Use `FT_Get_BDF_Charset_ID' to access the encoding and registry.
+
+The driver always exports `ft_encoding_none' as face->charmap.encoding.
+FT_Get_Char_Index() behavior is unmodified, that is, it converts the ULong
+value given as argument into the corresponding glyph number.
+
+
+Known problems
+**************
+
+- dealing explicitly with encodings breaks the uniformity of FreeType 2
+ API.
+
+- except for encodings properties, client applications have no
+ visibility of the PCF_Face object. This means that applications
+ cannot directly access font tables and are obliged to trust
+ FreeType.
+
+- currently, glyph names and ink_metrics are ignored.
+
+I plan to give full visibility of the PCF_Face object in the next
+release of the driver, thus implementing also glyph names and
+ink_metrics.
+
+- height is defined as (ascent - descent). Is this correct?
+
+- if unable to read size information from the font, PCF_Init_Face
+ sets available_size->width and available_size->height to 12.
+
+- too many english grammar errors in the readme file :-(

+ * A `CF2_Blues' object stores the blue zones (horizontal alignment
+ * zones) of a font. These are specified in the CFF private dictionary
+ * by `BlueValues', `OtherBlues', `FamilyBlues', and `FamilyOtherBlues'.
+ * Each zone is defined by a top and bottom edge in character space.
+ * Further, each zone is either a top zone or a bottom zone, as recorded
+ * by `bottomZone'.
+ *
+ * The maximum number of `BlueValues' and `FamilyBlues' is 7 each.
+ * However, these are combined to produce a total of 7 zones.
+ * Similarly, the maximum number of `OtherBlues' and `FamilyOtherBlues'
+ * is 5 and these are combined to produce an additional 5 zones.
+ *
+ * Blue zones are used to `capture' hints and force them to a common
+ * alignment point. This alignment is recorded in device space in
+ * `dsFlatEdge'. Except for this value, a `CF2_Blues' object could be
+ * constructed independently of scaling. Construction may occur once
+ * the matrix is known. Other features implemented in the Capture
+ * method are overshoot suppression, overshoot enforcement, and Blue
+ * Boost.
+ *
+ * Capture is determined by `BlueValues' and `OtherBlues', but the
+ * alignment point may be adjusted to the scaled flat edge of
+ * `FamilyBlues' or `FamilyOtherBlues'. No alignment is done to the

+ * A poor-man error facility.
+ *
+ * This code being written in vanilla C, doesn't have the luxury of a
+ * language-supported exception mechanism such as the one available in
+ * Java. Instead, we are stuck with using error codes that must be
+ * carefully managed and preserved. However, it is convenient for us to
+ * model our error mechanism on a Java-like exception mechanism.
+ * When we assign an error code we are thus `throwing' an error.
+ *
+ * The preservation of an error code is done by coding convention.
+ * Upon a function call if the error code is anything other than
+ * `FT_Err_Ok', which is guaranteed to be zero, we
+ * will return without altering that error. This will allow the
+ * error to propagate and be handled at the appropriate location in
+ * the code.
+ *
+ * This allows a style of code where the error code is initialized
+ * up front and a block of calls are made with the error code only
+ * being checked after the block. If a new error occurs, the original
+ * error will be preserved and a functional no-op should result in any
+ * subsequent function that has an initial error code not equal to
+ * `FT_Err_Ok'.
+ *
+ * Errors are encoded by calling the `FT_THROW' macro. For example,
+ *
+ * {
+ * FT_Error e;
+ *
+ *
+ * ...
+ * e = FT_THROW( Out_Of_Memory );

+ *
+ * A simple technical note on how the raster works
+ * -----------------------------------------------
+ *
+ * Converting an outline into a bitmap is achieved in several steps:
+ *
+ * 1 - Decomposing the outline into successive `profiles'. Each
+ * profile is simply an array of scanline intersections on a given
+ * dimension. A profile's main attributes are
+ *
+ * o its scanline position boundaries, i.e. `Ymin' and `Ymax'
+ *
+ * o an array of intersection coordinates for each scanline
+ * between `Ymin' and `Ymax'
+ *
+ * o a direction, indicating whether it was built going `up' or
+ * `down', as this is very important for filling rules
+ *
+ * o its drop-out mode
+ *
+ * 2 - Sweeping the target map's scanlines in order to compute segment
+ * `spans' which are then filled. Additionally, this pass
+ * performs drop-out control.
+ *
+ * The outline data is parsed during step 1 only. The profiles are
+ * built from the bottom of the render pool, used as a stack. The
+ * following graphics shows the profile list under construction:
+ *
+ * __________________________________________________________ _ _
+ * | | | | |
+ * | profile | coordinates for | profile | coordinates for |-->
+ * | 1 | profile 1 | 2 | profile 2 |-->
+ * |_________|_________________|_________|_________________|__ _ _
+ *
+ * ^ ^
+ * | |
+ * start of render pool top
+ *
+ * The top of the profile stack is kept in the `top' variable.
+ *
+ * As you can see, a profile record is pushed on top of the render
+ * pool, which is then followed by its coordinates/intersections. If
+ * a change of direction is detected in the outline, a new profile is
+ * generated until the end of the outline.
+ *
+ * Note that when all profiles have been generated, the function
+ * Finalize_Profile_Table() is used to record, for each profile, its
+ * bottom-most scanline as well as the scanline above its upmost
+ * boundary. These positions are called `y-turns' because they (sort
+ * of) correspond to local extrema. They are stored in a sorted list
+ * built from the top of the render pool as a downwards stack:
+ *
+ * _ _ _______________________________________
+ * | |
+ * <--| sorted list of |
+ * <--| extrema scanlines |
+ * _ _ __________________|____________________|
+ *
+ * ^ ^
+ * | |
+ * maxBuff sizeBuff = end of pool
+ *
+ * This list is later used during the sweep phase in order to
+ * optimize performance (see technical note on the sweep below).
+ *
+ * Of course, the raster detects whether the two stacks collide and
+ * handles the situation properly.

+ * A brief technical overview of how the BSDF rasterizer works
+ * -----------------------------------------------------------
+ *
+ * [Notes]:
+ * * SDF stands for Signed Distance Field everywhere.
+ *
+ * * BSDF stands for Bitmap to Signed Distance Field rasterizer.
+ *
+ * * This renderer converts rasterized bitmaps to SDF. There is another
+ * renderer called 'sdf', which generates SDF directly from outlines;
+ * see file `ftsdf.c` for more.
+ *
+ * * The idea of generating SDF from bitmaps is taken from two research
+ * papers, where one is dependent on the other:
+ *
+ * - Per-Erik Danielsson: Euclidean Distance Mapping
+ * http://webstaff.itn.liu.se/~stegu/JFA/Danielsson.pdf
+ *
+ * From this paper we use the eight-point sequential Euclidean
+ * distance mapping (8SED). This is the heart of the process used
+ * in this rasterizer.
+ *
+ * - Stefan Gustavson, Robin Strand: Anti-aliased Euclidean distance transform.

+ *
+ * The original 8SED algorithm discards the pixels' alpha values,
+ * which can contain information about the actual outline of the
+ * glyph. This paper takes advantage of those alpha values and
+ * approximates outline pretty accurately.
+ *
+ * * This rasterizer also works for monochrome bitmaps. However, the
+ * result is not as accurate since we don't have any way to
+ * approximate outlines from binary bitmaps.
+ *
+ * ========================================================================
+ *
+ * Generating SDF from bitmap is done in several steps.
+ *
+ * (1) The only information we have is the bitmap itself. It can
+ * be monochrome or anti-aliased. If it is anti-aliased, pixel values
+ * are nothing but coverage values. These coverage values can be used
+ * to extract information about the outline of the image. For
+ * example, if the pixel's alpha value is 0.5, then we can safely
+ * assume that the outline passes through the center of the pixel.
+ *
+ * (2) Find edge pixels in the bitmap (see `bsdf_is_edge` for more). For
+ * all edge pixels we use the Anti-aliased Euclidean distance
+ * transform algorithm and compute approximate edge distances (see
+ * `compute_edge_distance` and/or the second paper for more).
+ *
+ * (3) Now that we have computed approximate distances for edge pixels we
+ * use the 8SED algorithm to basically sweep the entire bitmap and
+ * compute distances for the rest of the pixels. (Since the algorithm
+ * is pretty convoluted it is only explained briefly in a comment to
+ * function `edt8`. To see the actual algorithm refer to the first
+ * paper.)
+ *
+ * (4) Finally, compute the sign for each pixel. This is done in function
+ * `finalize_sdf`. The basic idea is that if a pixel's original
+ * alpha/coverage value is greater than 0.5 then it is 'inside' (and
+ * 'outside' otherwise).
+ *
+ * Pseudo Code:
+ *
+ * ```
+ * b = source bitmap;
+ * t = target bitmap;
+ * dm = list of distances; // dimension equal to b
+ *
+ * foreach grid_point (x, y) in b:
+ * {
+ * if (is_edge(x, y)):
+ * dm = approximate_edge_distance(b, x, y);
+ *
+ * // do the 8SED on the distances
+ * edt8(dm);
+ *
+ * // determine the signs
+ * determine_signs(dm):
+ *
+ * // copy SDF data to the target bitmap
+ * copy(dm to t);
+ * }

+ * (1) In anti-aliased images, the pixel's alpha value is the coverage

+ * the pixel.
+ *
+ * (2) For this reason we can use that alpha value to approximate the real

+ * different approximation which is quite accurate even for
+ * non-axis-aligned edges.
+ *
+ * (3) The only remaining piece of information that we cannot
+ * approximate directly from the alpha is the direction of the edge.
+ * This is where we use Sobel's operator to compute the gradient of
+ * the pixel. The gradient give us a pretty good approximation of
+ * the edge direction. We use a 3x3 kernel filter to compute the
+ * gradient.

+ *
+ * A brief technical overview of how the SDF rasterizer works
+ * ----------------------------------------------------------
+ *
+ * [Notes]:
+ * * SDF stands for Signed Distance Field everywhere.
+ *
+ * * This renderer generates SDF directly from outlines. There is
+ * another renderer called 'bsdf', which converts bitmaps to SDF; see
+ * file `ftbsdf.c` for more.
+ *
+ * * The basic idea of generating the SDF is taken from Viktor Chlumsky's
+ * research paper. The paper explains both single and multi-channel
+ * SDF, however, this implementation only generates single-channel SDF.
+ *
+ * Chlumsky, Viktor: Shape Decomposition for Multi-channel Distance
+ * Fields. Master's thesis. Czech Technical University in Prague,
+ * Faculty of InformationTechnology, 2015.
+ *
+ * For more information: https://github.com/Chlumsky/msdfgen
+ *
+ * ========================================================================
+ *
+ * Generating SDF from outlines is pretty straightforward.
+ *
+ * (1) We have a set of contours that make the outline of a shape/glyph.
+ * Each contour comprises of several edges, with three types of edges.
+ *
+ * * line segments
+ * * conic Bezier curves
+ * * cubic Bezier curves
+ *
+ * (2) Apart from the outlines we also have a two-dimensional grid, namely
+ * the bitmap that is used to represent the final SDF data.
+ *
+ * (3) In order to generate SDF, our task is to find shortest signed
+ * distance from each grid point to the outline. The 'signed
+ * distance' means that if the grid point is filled by any contour
+ * then its sign is positive, otherwise it is negative. The pseudo
+ * code is as follows.
+ *
+ * ```
+ * foreach grid_point (x, y):
+ * {
+ * int min_dist = INT_MAX;
+ *
+ * foreach contour in outline:
+ * {
+ * foreach edge in contour:
+ * {
+ * // get shortest distance from point (x, y) to the edge
+ * d = get_min_dist(x, y, edge);
+ *
+ * if (d < min_dist)
+ * min_dist = d;
+ * }
+ *
+ * bitmap[x, y] = min_dist;
+ * }
+ * }
+ * ```
+ *
+ * (4) After running this algorithm the bitmap contains information about
+ * the shortest distance from each point to the outline of the shape.
+ * Of course, while this is the most straightforward way of generating
+ * SDF, we use various optimizations in our implementation. See the
+ * `sdf_generate_*' functions in this file for all details.
+ *
+ * The optimization currently used by default is subdivision; see
+ * function `sdf_generate_subdivision` for more.
+ *
+ * Also, to see how we compute the shortest distance from a point to
+ * each type of edge, check out the `get_min_distance_*' functions.

+ *
+ * @Description:
+ * At some places on the grid two edges can give opposite directions;
+ * this happens when the closest point is on one of the endpoint. In
+ * that case we need to check the proper sign.
+ *
+ * This can be visualized by an example:
+ *
+ * ```
+ * x
+ *
+ * o
+ * ^ \
+ * / \
+ * / \
+ * (a) / \ (b)
+ * / \
+ * / \
+ * / v
+ * ```
+ *
+ * Suppose `x` is the point whose shortest distance from an arbitrary
+ * contour we want to find out. It is clear that `o` is the nearest
+ * point on the contour. Now to determine the sign we do a cross
+ * product of the shortest distance vector and the edge direction, i.e.,
+ *
+ * ```
+ * => sign = cross(x - o, direction(a))
+ * ```
+ *
+ * Using the right hand thumb rule we can see that the sign will be
+ * positive.
+ *
+ * If we use `b', however, we have
+ *
+ * ```
+ * => sign = cross(x - o, direction(b))
+ * ```
+ *
+ * In this case the sign will be negative. To determine the correct
+ * sign we thus divide the plane in two halves and check which plane the
+ * point lies in.
+ *
+ * ```
+ * |
+ * x |
+ * |
+ * o
+ * ^|\
+ * / | \
+ * / | \
+ * (a) / | \ (b)
+ * / | \
+ * / \
+ * / v
+ * ```
+ *
+ * We can see that `x` lies in the plane of `a`, so we take the sign
+ * determined by `a`. This test can be easily done by calculating the
+ * orthogonality and taking the greater one.
+ *
+ * The orthogonality is simply the sinus of the two vectors (i.e.,
+ * x - o) and the corresponding direction. We efficiently pre-compute
+ * the orthogonality with the corresponding `get_min_distance_*`
+ * functions.
+ *

+ * The correct signed distance, which is computed by using the above
+ * algorithm.

+ * The function does not care about the actual distance, it simply

+ * are fairly apart. In that case simply use the signed distance with
+ * a shorter absolute distance.

+ * p1 = first control point
+ * p2 = second control point

+ * flip_sign ::
+ * By default positive values indicate positions inside of contours,

+ * are intended to allow applications to lay out documents in a
+ * typographically-correct and portable fashion.

+ * compatibility, operating systems and applications doing whatever
+ * they want, not to mention broken fonts.
+ *
+ * Not all fonts have an OS/2 table; in this case, we take the values
+ * in the horizontal header, although there is nothing stopping the
+ * values from being unreliable. Even with a OS/2 table, certain fonts
+ * set the sTypoAscender, sTypoDescender and sTypoLineGap fields to 0
+ * and instead correctly set usWinAscent and usWinDescent.
+ *
+ * As an example, Arial Narrow is shipped as four files ARIALN.TTF,
+ * ARIALNI.TTF, ARIALNB.TTF and ARIALNBI.TTF. Strangely, all fonts have
+ * the same values in their sTypo* fields, except ARIALNB.ttf which
+ * sets them to 0. All of them have different usWinAscent/Descent
+ * values. The OS/2 table therefore cannot be trusted for computing the
+ * text height reliably.
+ *
+ * As a compromise, do the following:
+ *
+ * 1. If the OS/2 table exists and the fsSelection bit 7 is set
+ * (USE_TYPO_METRICS), trust the font and use the sTypo* metrics.
+ * 2. Otherwise, use the `hhea' table's metrics.
+ * 3. If they are zero and the OS/2 table exists,
+ * 1. use the OS/2 table's sTypo* metrics if they are non-zero.
+ * 2. Otherwise, use the OS/2 table's usWin* metrics.

+ *
+ * The `keys' table is used to map charcode high bytes to sub-headers.
+ * The value of `NSUBS' is the number of sub-headers defined in the
+ * table and is computed by finding the maximum of the `keys' table.
+ *
+ * Note that for any `n', `keys[n]' is a byte offset within the `subs'
+ * table, i.e., it is the corresponding sub-header index multiplied
+ * by 8.
+ *
+ * Each sub-header has the following format.
+ *
+ * NAME OFFSET TYPE DESCRIPTION
+ *
+ * first 0 USHORT first valid low-byte
+ * count 2 USHORT number of valid low-bytes
+ * delta 4 SHORT see below
+ * offset 6 USHORT see below
+ *
+ * A sub-header defines, for each high byte, the range of valid
+ * low bytes within the charmap. Note that the range defined by `first'
+ * and `count' must be completely included in the interval [0..255]
+ * according to the specification.
+ *
+ * If a character code is contained within a given sub-header, then
+ * mapping it to a glyph index is done as follows.
+ *
+ * - The value of `offset' is read. This is a _byte_ distance from the
+ * location of the `offset' field itself into a slice of the
+ * `glyph_ids' table. Let's call it `slice' (it is a USHORT[], too).
+ *
+ * - The value `slice[char.lo - first]' is read. If it is 0, there is
+ * no glyph for the charcode. Otherwise, the value of `delta' is
+ * added to it (modulo 65536) to form a new glyph index.
+ *
+ * It is up to the validation routine to check that all offsets fall
+ * within the glyph IDs table (and not within the `subs' table itself or
+ * outside of the CMap).

+ * Character codes are modelled by a series of ordered (increasing)

+ * not overlap, and the last segment should always contain the value

+ *
+ * The fields `searchRange', `entrySelector' and `rangeShift' are better
+ * ignored (they are traces of over-engineering in the TrueType
+ * specification).
+ *
+ * Each segment also has a signed `delta', as well as an optional offset
+ * within the `glyphIds' table.
+ *
+ * If a segment's idOffset is 0, the glyph index corresponding to any
+ * charcode within the segment is obtained by adding the value of
+ * `idDelta' directly to the charcode, modulo 65536.
+ *
+ * Otherwise, a glyph index is taken from the glyph IDs sub-array for
+ * the segment, and the value of `idDelta' is added to it.
+ *
+ *
+ * Finally, note that a lot of fonts contain an invalid last segment,
+ * where `start' and `end' are correctly set to 0xFFFF but both `delta'
+ * and `offset' are incorrect (e.g., `opens___.ttf' which comes with
+ * OpenOffice.org). We need special code to deal with them correctly.

+ /***** `char_hi' and `char_lo' must be in the Surrogates Area. *****/

+ *
+ * This is a new anti-aliasing scan-converter for FreeType 2. The
+ * algorithm used here is _very_ different from the one in the standard
+ * `ftraster' module. Actually, `ftgrays' computes the _exact_
+ * coverage of the outline on each pixel cell by straight segments.
+ *
+ * It is based on ideas that I initially found in Raph Levien's
+ * excellent LibArt graphics library (see https://www.levien.com/libart
+ * for more information, though the web pages do not tell anything
+ * about the renderer; you'll have to dive into the source code to
+ * understand how it works).
+ *
+ * Note, however, that this is a _very_ different implementation
+ * compared to Raph's. Coverage information is stored in a very
+ * different way, and I don't use sorted vector paths. Also, it doesn't
+ * use floating point values.
+ *
+ * Bézier segments are flattened by splitting them until their deviation
+ * from straight line becomes much smaller than a pixel. Therefore, the
+ * pixel coverage by a Bézier curve is calculated approximately. To
+ * estimate the deviation, we use the distance from the control point
+ * to the conic chord centre or the cubic chord trisection. These
+ * distances vanish fast after each split. In the conic case, they vanish
+ * predictably and the number of necessary splits can be calculated.
+ *
+ * This renderer has the following advantages:
+ *
+ * - It doesn't need an intermediate bitmap. Instead, one can supply a
+ * callback function that will be called by the renderer to draw gray
+ * spans on any target surface. You can thus do direct composition on
+ * any kind of bitmap, provided that you give the renderer the right
+ * callback.
+ *
+ * - A perfect anti-aliaser, i.e., it computes the _exact_ coverage on
+ * each pixel cell by straight segments.
+ *
+ * - It performs a single pass on the outline (the `standard' FT2
+ * renderer makes two passes).
+ *
+ * - It can easily be modified to render to _any_ number of gray levels
+ * cheaply.
+ *
+ * - For small (< 80) pixel sizes, it is faster than the standard
+ * renderer.

+ftrandom
+========
+
+This program expects a set of directories containing good fonts, and a set
+of extensions of fonts to be tested. It will randomly pick a font, copy it,
+introduce an error and then test it.
+
+The FreeType tests are quite basic; for each erroneous font ftrandom
+
+ . forks off a new tester,
+ . initializes the library,
+ . opens each font in the file,
+ . loads each glyph,
+ . optionally reviews the contours of the glyph,
+ . optionally rasterizes the glyph, and
+ . closes the face.
+
+If a tester takes longer than 20 seconds, ftrandom saves the erroneous font
+and continues. If the tester exits normally or with an error, then the
+superstructure removes the test font and continues.
+
+
+Command line options
+--------------------
+
+ --all Test every font in the directory(ies) no matter
+ what its extension.
+ --check-outlines Call `FT_Outline_Decompose' on each glyph.
+ --dir <dir> Append <dir> to the list of directories to search
+ for good fonts. No recursive search.
+ --error-count <cnt> Introduce <cnt> single-byte errors into the
+ erroneous fonts (default: 1).
+ --error-fraction <frac> Multiply the file size of the font by <frac> and
+ introduce that many errors into the erroneous
+ font file. <frac> should be in the range [0;1]
+ (default: 0.0).
+ --ext <ext> Add <ext> to the set of font types tested.
+ --help Print out this list of options.
+ --nohints Specify FT_LOAD_NO_HINTING when loading glyphs.
+ --rasterize Call `FT_Render_Glyph' as well as loading it.
+ --result <dir> This is the directory in which test files are
+ placed.
+ --test <file> Run a single test on a pre-generated testcase.
+ This is done in the current process so it can be
+ debugged more easily.
+
+The default font extensions tested by ftrandom are
+
+ .ttf .otf .ttc .cid .pfb .pfa .bdf .pcf .pfr .fon .otb .cff
+
+The default font directory is controlled by the macro `GOOD_FONTS_DIR' in
+the source code (and can be thus specified during compilation); its default
+value is
+
+ /usr/local/share/fonts
+
+The default result directory is `results' (in the current directory).
+
+
+Compilation
+-----------
+
+Two possible solutions.
+
+. Run ftrandom within a debugging tool like `valgrind' to catch various
+ memory issues.
+
+. Compile FreeType with sanitizer flags as provided by gcc or clang, for
+ example, then link it with ftrandom.

+# We now store the Adobe Glyph List in compressed form. The list is put
+# into a data structure called `trie' (because it has a tree-like
+# appearance). Consider, for example, that you want to store the
+# following name mapping:
+#
+# A => 1
+# Aacute => 6
+# Abalon => 2
+# Abstract => 4
+#
+# It is possible to store the entries as follows.
+#
+# A => 1
+# |
+# +-acute => 6
+# |
+# +-b
+# |
+# +-alon => 2
+# |
+# +-stract => 4
+#
+# We see that each node in the trie has:
+#
+# - one or more `letters'
+# - an optional value
+# - zero or more child nodes
+#
+# The first step is to call
+#
+# root = StringNode( "", 0 )
+# for word in map.values():
+# root.add( word, map[word] )
+#
+# which creates a large trie where each node has only one children.
+#
+# Executing
+#
+# root = root.optimize()
+#
+# optimizes the trie by merging the letters of successive nodes whenever
+# possible.
+#
+# Each node of the trie is stored as follows.
+#
+# - First the node's letter, according to the following scheme. We
+# use the fact that in the AGL no name contains character codes > 127.
+#
+# name bitsize description
+# ----------------------------------------------------------------
+# notlast 1 Set to 1 if this is not the last letter
+# in the word.
+# ascii 7 The letter's ASCII value.
+#
+# - The letter is followed by a children count and the value of the
+# current key (if any). Again we can do some optimization because all
+# AGL entries are from the BMP; this means that 16 bits are sufficient
+# to store its Unicode values. Additionally, no node has more than
+# 127 children.
+#
+# name bitsize description
+# -----------------------------------------
+# hasvalue 1 Set to 1 if a 16-bit Unicode value follows.
+# num_children 7 Number of children. Can be 0 only if
+# `hasvalue' is set to 1.
+# value 16 Optional Unicode value.
+#
+# - A node is finished by a list of 16bit absolute offsets to the
+# children, which must be sorted in increasing order of their first
+# letter.
+#
+# For simplicity, all 16bit quantities are stored in big-endian order.

+ *
+ * Note that the rounding to the grid (in the device space) is not

+ *
+ * However, the specification lacks the precise definition of vertical
+ * phantom points. Greg Hitchcock provided the following explanation.
+ *
+ * - a `vmtx' table is present
+ *
+ * For any glyph, the minimum and maximum y values (`ymin' and `ymax')
+ * are given in the `glyf' table, the top side bearing (tsb) and advance
+ * height (ah) are given in the `vmtx' table. The bottom side bearing
+ * (bsb) is then calculated as
+ *
+ * bsb = ah - (tsb + ymax - ymin) ,
+ *
+ * and the initial position of vertical phantom points is
+ *
+ * pp3 = (x, round(ymax + tsb)) ,
+ * pp4 = (x, round(pp3 - ah)) .
+ *
+ * See below for value `x'.
+ *
+ * - no `vmtx' table in the font
+ *
+ * If there is an `OS/2' table, we set
+ *
+ * DefaultAscender = sTypoAscender ,
+ * DefaultDescender = sTypoDescender ,
+ *
+ * otherwise we use data from the `hhea' table:
+ *
+ * DefaultAscender = Ascender ,
+ * DefaultDescender = Descender .
+ *
+ * With these two variables we can now set
+ *
+ * ah = DefaultAscender - sDefaultDescender ,
+ * tsb = DefaultAscender - yMax ,
+ *
+ * and proceed as if a `vmtx' table was present.
+ *
+ * Usually we have
+ *
+ * x = aw / 2 , (1)
+ *
+ * but there is one compatibility case where it can be set to
+ *
+ * x = -DefaultDescender -
+ * ((DefaultAscender - DefaultDescender - aw) / 2) . (2)
+ *
+ * and another one with
+ *
+ * x = 0 . (3)

+ /*
+ * FreeType supports ClearType-like hinting of TrueType fonts through
+ * the version 40 interpreter. This is achieved through several hacks
+ * in the base (v35) interpreter, as detailed below.
+ *
+ * ClearType is an umbrella term for several rendering techniques
+ * employed by Microsoft's various GUI and rendering toolkit
+ * implementations, most importantly: subpixel rendering for using the
+ * RGB subpixels of LCDs to approximately triple the perceived
+ * resolution on the x-axis and subpixel hinting for positioning stems
+ * on subpixel borders. TrueType programming is explicit, i.e., fonts
+ * must be programmed to take advantage of ClearType's possibilities.
+ *
+ * When ClearType was introduced, it seemed unlikely that all fonts
+ * would be reprogrammed, so Microsoft decided to implement a backward
+ * compatibility mode. It employs several simple to complicated
+ * assumptions and tricks, many of them font-dependent, that modify the
+ * interpretation of the bytecode contained in these fonts to retrofit
+ * them into a ClearType-y look. The quality of the results varies.
+ * Most (web)fonts that were released since then have come to rely on
+ * these hacks to render correctly, even some of Microsoft's flagship
+ * fonts (e.g., Calibri, Cambria, Segoe UI).
+ *
+ * FreeType's minimal subpixel hinting code (interpreter version 40)
+ * employs a small list of font-agnostic hacks loosely based on the
+ * public information available on Microsoft's compatibility mode[2].
+ * The focus is on modern (web)fonts rather than legacy fonts that were
+ * made for monochrome rendering. It will not match ClearType rendering
+ * exactly. Unlike the `Infinality' code (interpreter version 38) that
+ * came before, it will not try to toggle hacks for specific fonts for
+ * performance and complexity reasons. It will fall back to version 35
+ * behavior for tricky fonts[1] or when monochrome rendering is
+ * requested.
+ *
+ * Major hacks
+ *
+ * - Any point movement on the x axis is ignored (cf. `Direct_Move' and
+ * `Direct_Move_X'). This has the smallest code footprint and single
+ * biggest effect. The ClearType way to increase resolution is
+ * supersampling the x axis, the FreeType way is ignoring instructions
+ * on the x axis, which gives the same result in the majority of
+ * cases.
+ *
+ * - Points are not moved post-IUP (neither on the x nor on the y axis),
+ * except the x component of diagonal moves post-IUP (cf.
+ * `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point'). Post-IUP
+ * changes are commonly used to `fix' pixel patterns which has little
+ * use outside monochrome rendering.
+ *
+ * - SHPIX and DELTAP don't execute unless moving a composite on the
+ * y axis or moving a previously y touched point. SHPIX additionally
+ * denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP').
+ * Both instructions are commonly used to `fix' pixel patterns for
+ * monochrome or Windows's GDI rendering but make little sense for
+ * FreeType rendering. Both can distort the outline. See [2] for
+ * details.
+ *
+ * - The hdmx table and modifications to phantom points are ignored.
+ * Bearings and advance widths remain unchanged (except rounding them
+ * outside the interpreter!), cf. `compute_glyph_metrics' and
+ * `TT_Hint_Glyph'. Letting non-native-ClearType fonts modify spacing
+ * might mess up spacing.
+ *
+ * Minor hacks
+ *
+ * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP. This
+ * prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at
+ * various sizes.
+ *
+ * (Post-IUP is the state after both IUP[x] and IUP[y] have been
+ * executed.)
+ *
+ * The best results are achieved for fonts that were from the outset
+ * designed with ClearType in mind, meaning they leave the x axis mostly
+ * alone and don't mess with the `final' outline to produce more
+ * pleasing pixel patterns. The harder the designer tried to produce
+ * very specific patterns (`superhinting') for pre-ClearType-displays,
+ * the worse the results.
+ *
+ * Microsoft defines a way to turn off backward compatibility and
+ * interpret instructions as before (called `native ClearType')[2][3].
+ * The font designer then regains full control and is responsible for
+ * making the font work correctly with ClearType without any
+ * hand-holding by the interpreter or rasterizer[4]. The v40
+ * interpreter assumes backward compatibility by default, which can be
+ * turned off the same way by executing the following in the control
+ * program (cf. `Ins_INSTCTRL').
+ *
+ * #PUSH 4,3
+ * INSTCTRL[]
+ *
+ * [1] Tricky fonts as FreeType defines them rely on the bytecode
+ * interpreter to display correctly. Hacks can interfere with them,
+ * so they get treated like native ClearType fonts (v40 with
+ * backward compatibility turned off). Cf. `TT_RunIns'.
+ *
+ * [2] Proposed by Microsoft's Greg Hitchcock in
+ * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
+ *
+ * [3] Beat Stamm describes it in more detail:
+ * http://rastertragedy.com/RTRCh4.htm#Sec12.
+ *
+ * [4] The list of `native ClearType' fonts is small at the time of this
+ * writing; I found the following on a Windows 10 Update 1511
+ * installation: Constantia, Corbel, Sitka, Malgun Gothic, Microsoft
+ * JhengHei (Bold and UI Bold), Microsoft YaHei (Bold and UI Bold),
+ * SimSun, NSimSun, and Yu Gothic.

+ * A note regarding non-squared pixels:
+ *
+ * (This text will probably go into some docs at some time; for now, it
+ * is kept here to explain some definitions in the TT_Size_Metrics
+ * record).
+ *
+ * The CVT is a one-dimensional array containing values that control
+ * certain important characteristics in a font, like the height of all
+ * capitals, all lowercase letter, default spacing or stem width/height.
+ *
+ * These values are found in FUnits in the font file, and must be scaled
+ * to pixel coordinates before being used by the CVT and glyph programs.
+ * Unfortunately, when using distinct x and y resolutions (or distinct x
+ * and y pointsizes), there are two possible scalings.
+ *
+ * A first try was to implement a `lazy' scheme where all values were
+ * scaled when first used. However, while some values are always used
+ * in the same direction, some others are used under many different
+ * circumstances and orientations.
+ *
+ * I have found a simpler way to do the same, and it even seems to work
+ * in most of the cases:
+ *
+ * - All CVT values are scaled to the maximum ppem size.
+ *
+ * - When performing a read or write in the CVT, a ratio factor is used
+ * to perform adequate scaling. Example:
+ *
+ * x_ppem = 14
+ * y_ppem = 10
+ *
+ * We choose ppem = x_ppem = 14 as the CVT scaling size. All cvt
+ * entries are scaled to it.
+ *
+ * x_ratio = 1.0
+ * y_ratio = y_ppem/ppem (< 1.0)
+ *
+ * We compute the current ratio like:
+ *
+ * - If projVector is horizontal,
+ * ratio = x_ratio = 1.0
+ *
+ * - if projVector is vertical,
+ * ratio = y_ratio
+ *
+ * - else,
+ * ratio = sqrt( (proj.x * x_ratio) ^ 2 + (proj.y * y_ratio) ^ 2 )
+ *
+ * Reading a cvt value returns
+ * ratio * cvt[index]
+ *
+ * Writing a cvt value in pixels:
+ * cvt[index] / ratio
+ *
+ * The current ppem is simply
+ * ratio * ppem

+ * These rules affect how the TT Interpreter does hinting, with the
+ * goal of doing subpixel hinting by (in general) ignoring x moves.
+ * Some of these rules are fixes that go above and beyond the
+ * stated techniques in the MS whitepaper on Cleartype, due to
+ * artifacts in many glyphs. So, these rules make some glyphs render
+ * better than they do in the MS rasterizer.
+ *
+ * "" string or 0 int/char indicates to apply to all glyphs.
+ * "-" used as dummy placeholders, but any non-matching string works.
+ *
+ * Some of this could arguably be implemented in fontconfig, however:
+ *
+ * - Fontconfig can't set things on a glyph-by-glyph basis.
+ * - The tweaks that happen here are very low-level, from an average
+ * user's point of view and are best implemented in the hinter.
+ *
+ * The goal is to make the subpixel hinting techniques as generalized
+ * as possible across all fonts to prevent the need for extra rules such
+ * as these.
+ *
+ * The rule structure is designed so that entirely new rules can easily
+ * be added when a new compatibility feature is discovered.

+ *
+ * This is the new and improved Type 1 data loader for FreeType 2. The
+ * old loader has several problems: it is slow, complex, difficult to
+ * maintain, and contains incredible hacks to make it accept some
+ * ill-formed Type 1 fonts without hiccup-ing. Moreover, about 5% of
+ * the Type 1 fonts on my machine still aren't loaded correctly by it.
+ *
+ * This version is much simpler, much faster and also easier to read and
+ * maintain by a great order of magnitude. The idea behind it is to
+ * _not_ try to read the Type 1 token stream with a state machine (i.e.
+ * a Postscript-like interpreter) but rather to perform simple pattern
+ * matching.
+ *
+ * Indeed, nearly all data definitions follow a simple pattern like
+ *
+ * ... /Field <data> ...
+ *
+ * where <data> can be a number, a boolean, a string, or an array of
+ * numbers. There are a few exceptions, namely the encoding, font name,
+ * charstrings, and subrs; they are handled with a special pattern
+ * matching routine.
+ *
+ * All other common cases are handled very simply. The matching rules
+ * are defined in the file `t1tokens.h' through the use of several
+ * macros calls PARSE_XXX. This file is included twice here; the first
+ * time to generate parsing callback functions, the second time to
+ * generate a table of keywords (with pointers to the associated
+ * callback functions).
+ *
+ * The function `parse_dict' simply scans *linearly* a given dictionary
+ * (either the top-level or private one) and calls the appropriate
+ * callback when it encounters an immediate keyword.
+ *
+ * This is by far the fastest way one can find to parse and read all
+ * data.
+ *
+ * This led to tremendous code size reduction. Note that later, the
+ * glyph loader will also be _greatly_ simplified, and the automatic
+ * hinter will replace the clumsy `t1hinter'.
