+A scaling algorithm that uses bilinear if not downscaling too much,
+and averaging otherwise (bilinear would produce poor results for big downscaling).
+
+By default the combination of two filters is used: bilinear and averaging algorithm. 
+Bilinear filtering is used for bitmap enlarging and shrinking till factor 0.6. Below
+this bilinear gives bad results because of limited sampling. For such cases averaging 
+is used which is a simple algorithm for shrinking. In averaging the algorithm 
+calculates the average of samples which result is the new pixel.

+    HACK: for scrollbars in case of thumb rect, page up and page down rect we
+    abuse the HitTestNativeScrollbar interface. All theming engines but macOS
+    are actually able to draw the thumb according to our internal representation.
+    However macOS draws a little outside. The canonical way would be to enhance the
+    HitTestNativeScrollbar passing a ScrollbarValue additionally so all necessary
+    information is available in the call.
+    .
+    However since there is only this one small exception we will deviate a little and
+    instead pass the respective rect as control region to allow for a small correction.
+
+    So all places using HitTestNativeScrollbar on ControlPart::ThumbHorz, ControlPart::ThumbVert,
+    ControlPart::TrackHorzLeft, ControlPart::TrackHorzRight, ControlPart::TrackVertUpper, ControlPart::TrackVertLower
+    do not use the control rectangle as region but the actual part rectangle, making
+    only small deviations feasible.

+/** Osnola:
+IMPORTANT NOTE: some Quickdraw lines/frames can not be "quickly" drawn exactly:
+for instance, when PenSize=(1,1), the line from (0,0) to (8,0)
+corresponds to the rectangle (0,0)(0,1)(9,1)(9,0), which can only be drawn
+ by drawing a rectangle. Drawing a non horizontal/vertical will imply to draw
+a polygon, ...
+Similarly, drawing the frame of a rectangle (0,0)(0,1)(9,1)(9,0) when PenSize=(1,1),
+will imply to draw a rectangle (0.5,0.5)(0.5,8.5)(8.5,8.5)(8.5,0.5) with linewidth=1...
+
+Here, we choose:
+- for horizontal/vertical lines and line with length less than five to draw the real line,
+- in the other case, we keep the same shape (even if this means some "bad" coordinates)

+ * Lossless image transformation routines.  These routines work on DCT
+ * coefficient arrays and thus do not require any lossy decompression
+ * or recompression of the image.
+ * Thanks to Guido Vollbeding for the initial design and code of this feature,
+ * and to Ben Jackson for introducing the cropping feature.
+ *
+ * Horizontal flipping is done in-place, using a single top-to-bottom
+ * pass through the virtual source array.  It will thus be much the
+ * fastest option for images larger than main memory.
+ *
+ * The other routines require a set of destination virtual arrays, so they
+ * need twice as much memory as jpegtran normally does.  The destination
+ * arrays are always written in normal scan order (top to bottom) because
+ * the virtual array manager expects this.  The source arrays will be scanned
+ * in the corresponding order, which means multiple passes through the source
+ * arrays for most of the transforms.  That could result in much thrashing
+ * if the image is larger than main memory.
+ *
+ * If cropping or trimming is involved, the destination arrays may be smaller
+ * than the source arrays.  Note it is not possible to do horizontal flip
+ * in-place when a nonzero Y crop offset is specified, since we'd have to move
+ * data from one block row to another but the virtual array manager doesn't
+ * guarantee we can touch more than one row at a time.  So in that case,
+ * we have to use a separate destination array.
+ *
+ * Some notes about the operating environment of the individual transform
+ * routines:
+ * 1. Both the source and destination virtual arrays are allocated from the
+ *    source JPEG object, and therefore should be manipulated by calling the
+ *    source's memory manager.
+ * 2. The destination's component count should be used.  It may be smaller
+ *    than the source's when forcing to grayscale.
+ * 3. Likewise the destination's sampling factors should be used.  When
+ *    forcing to grayscale the destination's sampling factors will be all 1,
+ *    and we may as well take that as the effective iMCU size.
+ * 4. When "trim" is in effect, the destination's dimensions will be the
+ *    trimmed values but the source's will be untrimmed.
+ * 5. When "crop" is in effect, the destination's dimensions will be the
+ *    cropped values but the source's will be uncropped.  Each transform
+ *    routine is responsible for picking up source data starting at the
+ *    correct X and Y offset for the crop region.  (The X and Y offsets
+ *    passed to the transform routines are measured in iMCU blocks of the
+ *    destination.)
+ * 6. All the routines assume that the source and destination buffers are
+ *    padded out to a full iMCU boundary.  This is true, although for the
+ *    source buffer it is an undocumented property of jdcoefct.c.

+/*
+ * Although rotating and flipping data expressed as DCT coefficients is not
+ * hard, there is an asymmetry in the JPEG format specification for images
+ * whose dimensions aren't multiples of the iMCU size.  The right and bottom
+ * image edges are padded out to the next iMCU boundary with junk data; but
+ * no padding is possible at the top and left edges.  If we were to flip
+ * the whole image including the pad data, then pad garbage would become
+ * visible at the top and/or left, and real pixels would disappear into the
+ * pad margins --- perhaps permanently, since encoders & decoders may not
+ * bother to preserve DCT blocks that appear to be completely outside the
+ * nominal image area.  So, we have to exclude any partial iMCUs from the
+ * basic transformation.
+ *
+ * Transpose is the only transformation that can handle partial iMCUs at the
+ * right and bottom edges completely cleanly.  flip_h can flip partial iMCUs
+ * at the bottom, but leaves any partial iMCUs at the right edge untouched.
+ * Similarly flip_v leaves any partial iMCUs at the bottom edge untouched.
+ * The other transforms are defined as combinations of these basic transforms
+ * and process edge blocks in a way that preserves the equivalence.
+ *
+ * The "trim" option causes untransformable partial iMCUs to be dropped;
+ * this is not strictly lossless, but it usually gives the best-looking
+ * result for odd-size images.  Note that when this option is active,
+ * the expected mathematical equivalences between the transforms may not hold.
+ * (For example, -rot 270 -trim trims only the bottom edge, but -rot 90 -trim
+ * followed by -rot 180 -trim trims both edges.)
+ *
+ * We also offer a lossless-crop option, which discards data outside a given
+ * image region but losslessly preserves what is inside.  Like the rotate and
+ * flip transforms, lossless crop is restricted by the JPEG format: the upper
+ * left corner of the selected region must fall on an iMCU boundary.  If this
+ * does not hold for the given crop parameters, we silently move the upper left
+ * corner up and/or left to make it so, simultaneously increasing the region
+ * dimensions to keep the lower right crop corner unchanged.  (Thus, the
+ * output image covers at least the requested region, but may cover more.)
+ * The adjustment of the region dimensions may be optionally disabled.
+ *
+ * We also provide a lossless-resize option, which is kind of a lossless-crop
+ * operation in the DCT coefficient block domain - it discards higher-order
+ * coefficients and losslessly preserves lower-order coefficients of a
+ * sub-block.
+ *
+ * Rotate/flip transform, resize, and crop can be requested together in a
+ * single invocation.  The crop is applied last --- that is, the crop region
+ * is specified in terms of the destination image after transform/resize.
+ *
+ * We also offer a "force to grayscale" option, which simply discards the
+ * chrominance channels of a YCbCr image.  This is lossless in the sense that
+ * the luminance channel is preserved exactly.  It's not the same kind of
+ * thing as the rotate/flip transformations, but it's convenient to handle it
+ * as part of this package, mainly because the transformation routines have to
+ * be aware of the option to know how many components to work on.

+ * as 'test1/test2/a-file.pdf\#thefragment) will be (hopefully) interpreted by the
+ * PDF reader (currently only Adobe Reader plug-in seems to be working that way) called
+ * from inside the Internet browser as: 'open the file test1/test2/a-file.pdf
+ * and go to named destination thefragment using default zoom'.
+ * The conversion is needed because in case of a fragment in the form: Slide%201
+ * (meaning Slide 1) as it is converted obeying the Inet rules, it will become Slide25201
+ * using this conversion, in both the generated named destinations, fragment and GoToR
+ * destination.
+ *
+ * The names for destinations are name objects and so they don't need to be encrypted
