+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006 Free Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about. Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+ Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+Pixman
+======
+
+Pixman is a library that provides low-level pixel manipulation
+features such as image compositing and trapezoid rasterization.
+
+Questions should be directed to the pixman mailing list:
+
+ https://lists.freedesktop.org/mailman/listinfo/pixman
+
+You can also file bugs at
+
+ https://gitlab.freedesktop.org/pixman/pixman/-/issues/new
+
+or submit improvements in form of a Merge Request via
+
+ https://gitlab.freedesktop.org/pixman/pixman/-/merge_requests
+
+For real time discussions about pixman, feel free to join the IRC
+channels #cairo and #xorg-devel on the FreeNode IRC network.
+
+
+Contributing
+------------
+
+In order to contribute to pixman, you will need a working knowledge of
+the git version control system. For a quick getting started guide,
+there is the "Everyday Git With 20 Commands Or So guide"
+
+ https://www.kernel.org/pub/software/scm/git/docs/everyday.html
+
+from the Git homepage. For more in depth git documentation, see the
+resources on the Git community documentation page:
+
+ https://git-scm.com/documentation
+
+Pixman uses the infrastructure from the freedesktop.org umbrella
+project. For instructions about how to use the git service on
+freedesktop.org, see:
+
+ https://www.freedesktop.org/wiki/Infrastructure/git/Developers
+
+The Pixman master repository can be found at:
+
+ https://gitlab.freedesktop.org/pixman/pixman
+
+
+Sending patches
+---------------
+
+Patches should be submitted in form of Merge Requests via Gitlab.
+
+You will first need to create a fork of the main pixman repository at
+
+ https://gitlab.freedesktop.org/pixman/pixman
+
+via the Fork button on the top right. Once that is done you can add your
+personal repository as a remote to your local pixman development git checkout:
+
+ git remote add my-gitlab git@gitlab.freedesktop.org:YOURUSERNAME/pixman.git
+
+ git fetch my-gitlab
+
+Make sure to have added ssh keys to your gitlab profile at
+
+ https://gitlab.freedesktop.org/profile/keys
+
+Once that is set up, the general workflow for sending patches is to create a
+new local branch with your improvements and once it's ready push it to your
+personal pixman fork:
+
+ git checkout -b fix-some-bug
+ ...
+ git push my-gitlab
+
+The output of the `git push` command will include a link that allows you to
+create a Merge Request against the official pixman repository.
+
+Whenever you make changes to your branch (add new commits or fix up commits)
+you push them back to your personal pixman fork:
+
+ git push -f my-gitlab
+
+If there is an open Merge Request Gitlab will automatically pick up the
+changes from your branch and pixman developers can review them anew.
+
+In order for your patches to be accepted, please consider the
+following guidelines:
+
+ - At each point in the series, pixman should compile and the test
+ suite should pass.
+
+ The exception here is if you are changing the test suite to
+ demonstrate a bug. In this case, make one commit that makes the
+ test suite fail due to the bug, and then another commit that fixes
+ the bug.
+
+ You can run the test suite with
+
+ make check
+
+ if you built pixman with autotools or
+
+ meson test -C builddir
+
+ if you built pixman with meson.
+
+ It will take around two minutes to run on a modern PC.
+
+ - Follow the coding style described in the CODING_STYLE file
+
+ - For bug fixes, include an update to the test suite to make sure
+ the bug doesn't reappear.
+
+ - For new features, add tests of the feature to the test
+ suite. Also, add a program demonstrating the new feature to the
+ demos/ directory.
+
+ - Write descriptive commit messages. Useful information to include:
+ - Benchmark results, before and after
+ - Description of the bug that was fixed
+ - Detailed rationale for any new API
+ - Alternative approaches that were rejected (and why they
+ don't work)
+ - If review comments were incorporated, a brief version
+ history describing what those changes were.
+
+ - For big patch series, write an introductory post with an overall
+ description of the patch series, including benchmarks and
+ motivation. Each commit message should still be descriptive and
+ include enough information to understand why this particular commit
+ was necessary.
+
+Pixman has high standards for code quality and so almost everybody
+should expect to have the first versions of their patches rejected.
+
+If you think that the reviewers are wrong about something, or that the
+guidelines above are wrong, feel free to discuss the issue. The purpose
+of the guidelines and code review is to ensure high code quality; it is
+not an exercise in compliance.

+ * calling convention and take up to 8 arguments:
+ * width, height, dst, dst_stride, src, src_stride, mask, mask_stride
+ *
+ * The arguments are ordered with the most important coming first (the
+ * first 4 arguments are passed to function in registers, the rest are
+ * on stack). The last arguments are optional, for example if the
+ * function is not using mask, then 'mask' and 'mask_stride' can be
+ * omitted when doing a function call.
+ *
+ * Arguments 'src' and 'mask' contain either a pointer to the top left
+ * pixel of the composited rectangle or a pixel color value depending
+ * on the function type. In the case of just a color value (solid source
+ * or mask), the corresponding stride argument is unused.

+ * Implementation of pixman_composite_over_8888_0565_asm_neon
+ *
+ * This function takes a8r8g8b8 source buffer, r5g6b5 destination buffer and
+ * performs OVER compositing operation. Function fast_composite_over_8888_0565
+ * from pixman-fast-path.c does the same in C and can be used as a reference.
+ *
+ * First we need to have some NEON assembly code which can do the actual
+ * operation on the pixels and provide it to the template macro.
+ *
+ * Template macro quite conveniently takes care of emitting all the necessary
+ * code for memory reading and writing (including quite tricky cases of
+ * handling unaligned leading/trailing pixels), so we only need to deal with
+ * the data in NEON registers.
+ *
+ * NEON registers allocation in general is recommented to be the following:
+ * d0, d1, d2, d3 - contain loaded source pixel data
+ * d4, d5, d6, d7 - contain loaded destination pixels (if they are needed)
+ * d24, d25, d26, d27 - contain loading mask pixel data (if mask is used)
+ * d28, d29, d30, d31 - place for storing the result (destination pixels)
+ *
+ * As can be seen above, four 64-bit NEON registers are used for keeping
+ * intermediate pixel data and up to 8 pixels can be processed in one step
+ * for 32bpp formats (16 pixels for 16bpp, 32 pixels for 8bpp).
+ *
+ * This particular function uses the following registers allocation:
+ * d0, d1, d2, d3 - contain loaded source pixel data
+ * d4, d5 - contain loaded destination pixels (they are needed)
+ * d28, d29 - place for storing the result (destination pixels)
+ */
+
+/*
+ * Step one. We need to have some code to do some arithmetics on pixel data.
+ * This is implemented as a pair of macros: '*_head' and '*_tail'. When used
+ * back-to-back, they take pixel data from {d0, d1, d2, d3} and {d4, d5},
+ * perform all the needed calculations and write the result to {d28, d29}.
+ * The rationale for having two macros and not just one will be explained
+ * later. In practice, any single monolitic function which does the work can
+ * be split into two parts in any arbitrary way without affecting correctness.
+ *
+ * There is one special trick here too. Common template macro can optionally
+ * make our life a bit easier by doing R, G, B, A color components
+ * deinterleaving for 32bpp pixel formats (and this feature is used in
+ * 'pixman_composite_over_8888_0565_asm_neon' function). So it means that
+ * instead of having 8 packed pixels in {d0, d1, d2, d3} registers, we
+ * actually use d0 register for blue channel (a vector of eight 8-bit
+ * values), d1 register for green, d2 for red and d3 for alpha. This
+ * simple conversion can be also done with a few NEON instructions:
+ *
+ * Packed to planar conversion:
+ * vuzp.8 d0, d1
+ * vuzp.8 d2, d3
+ * vuzp.8 d1, d3
+ * vuzp.8 d0, d2
+ *
+ * Planar to packed conversion:
+ * vzip.8 d0, d2
+ * vzip.8 d1, d3
+ * vzip.8 d2, d3
+ * vzip.8 d0, d1
+ *
+ * But pixel can be loaded directly in planar format using VLD4.8 NEON
+ * instruction. It is 1 cycle slower than VLD1.32, so this is not always
+ * desirable, that's why deinterleaving is optional.
+ *
+ * But anyway, here is the code:

+/*
+ * OK, now we got almost everything that we need. Using the above two
+ * macros, the work can be done right. But now we want to optimize
+ * it a bit. ARM Cortex-A8 is an in-order core, and benefits really
+ * a lot from good code scheduling and software pipelining.
+ *
+ * Let's construct some code, which will run in the core main loop.
+ * Some pseudo-code of the main loop will look like this:
+ * head
+ * while (...) {
+ * tail
+ * head
+ * }
+ * tail
+ *
+ * It may look a bit weird, but this setup allows to hide instruction
+ * latencies better and also utilize dual-issue capability more
+ * efficiently (make pairs of load-store and ALU instructions).
+ *
+ * So what we need now is a '*_tail_head' macro, which will be used
+ * in the core main loop. A trivial straightforward implementation
+ * of this macro would look like this:
+ *
+ * pixman_composite_over_8888_0565_process_pixblock_tail
+ * vst1.16 {d28, d29}, [DST_W, :128]!
+ * vld1.16 {d4, d5}, [DST_R, :128]!
+ * vld4.32 {d0, d1, d2, d3}, [SRC]!
+ * pixman_composite_over_8888_0565_process_pixblock_head
+ * cache_preload 8, 8
+ *
+ * Now it also got some VLD/VST instructions. We simply can't move from
+ * processing one block of pixels to the other one with just arithmetics.
+ * The previously processed data needs to be written to memory and new
+ * data needs to be fetched. Fortunately, this main loop does not deal
+ * with partial leading/trailing pixels and can load/store a full block
+ * of pixels in a bulk. Additionally, destination buffer is already
+ * 16 bytes aligned here (which is good for performance).
+ *
+ * New things here are DST_R, DST_W, SRC and MASK identifiers. These
+ * are the aliases for ARM registers which are used as pointers for
+ * accessing data. We maintain separate pointers for reading and writing
+ * destination buffer (DST_R and DST_W).
+ *
+ * Another new thing is 'cache_preload' macro. It is used for prefetching
+ * data into CPU L2 cache and improve performance when dealing with large
+ * images which are far larger than cache size. It uses one argument
+ * (actually two, but they need to be the same here) - number of pixels
+ * in a block. Looking into 'pixman-arm-neon-asm.h' can provide some
+ * details about this macro. Moreover, if good performance is needed
+ * the code from this macro needs to be copied into '*_tail_head' macro
+ * and mixed with the rest of code for optimal instructions scheduling.
+ * We are actually doing it below.
+ *
+ * Now after all the explanations, here is the optimized code.
+ * Different instruction streams (originaling from '*_head', '*_tail'
+ * and 'cache_preload' macro) use different indentation levels for
+ * better readability. Actually taking the code from one of these
+ * indentation levels and ignoring a few VLD/VST instructions would
+ * result in exactly the code from '*_head', '*_tail' or 'cache_preload'
+ * macro!

+ * FLAG_DEINTERLEAVE_32BPP - tells that we prefer to work with planar data

+ * - prefetch distance, measured in pixel blocks. In this case it is 5 times

+ * This file contains a macro ('generate_composite_function') which can

+ * Any combinations of source, destination and mask images with 8bpp,
+ * 16bpp, 24bpp, 32bpp color formats are supported.
+ *
+ * This macro takes care of:
+ * - handling of leading and trailing unaligned pixels
+ * - doing most of the work related to L2 cache preload
+ * - encourages the use of software pipelining for better instructions
+ * scheduling
+ *
+ * The user of this macro has to provide some configuration parameters
+ * (bit depths for the images, prefetch distance, etc.) and a set of
+ * macros, which should implement basic code chunks responsible for
+ * pixels processing. See 'pixman-arm-neon-asm.S' file for the usage
+ * examples.

+ * exactly two blocks of pixels

+ * This is a macro for implementing cache preload. The main idea is that
+ * cache preload logic is mostly independent from the rest of pixels
+ * processing code. It starts at the top left pixel and moves forward
+ * across pixels and can jump across scanlines. Prefetch distance is
+ * handled in an 'incremental' way: it starts from 0 and advances to the
+ * optimal distance over time. After reaching optimal prefetch distance,
+ * it is kept constant. There are some checks which prevent prefetching
+ * unneeded pixel lines below the image (but it still can prefetch a bit
+ * more data on the right side of the image - not a big issue and may
+ * be actually helpful when rendering text glyphs). Additional trick is
+ * the use of LDR instruction for prefetch instead of PLD when moving to
+ * the next line, the point is that we have a high chance of getting TLB
+ * miss in this case, and PLD would be useless.
+ *
+ * This sounds like it may introduce a noticeable overhead (when working with
+ * fully cached data). But in reality, due to having a separate pipeline and
+ * instruction queue for NEON unit in ARM Cortex-A8, normal ARM code can
+ * execute simultaneously with NEON and be completely shadowed by it. Thus
+ * we get no performance overhead at all (*). This looks like a very nice
+ * feature of Cortex-A8, if used wisely. We don't have a hardware prefetcher,
+ * but still can implement some rather advanced prefetch logic in software
+ * for almost zero cost!
+ *
+ * (*) The overhead of the prefetcher is visible when running some trivial
+ * pixels processing like simple copy. Anyway, having prefetch is a must
+ * when working with the graphics data.

+ * Because the alignment of pixel data to cachelines, and even the number of
+ * cachelines per row can vary from row to row, and because of the need to
+ * preload each scanline once and only once, this prefetch strategy treats
+ * each row of pixels independently. When a pixel row is long enough, there
+ * are three distinct phases of prefetch:
+ * * an inner loop section, where each time a cacheline of data is
+ * processed, another cacheline is preloaded (the exact distance ahead is
+ * determined empirically using profiling results from lowlevel-blt-bench)
+ * * a leading section, where enough cachelines are preloaded to ensure no
+ * cachelines escape being preloaded when the inner loop starts
+ * * a trailing section, where a limited number (0 or more) of cachelines
+ * are preloaded to deal with data (if any) that hangs off the end of the
+ * last iteration of the inner loop, plus any trailing bytes that were not
+ * enough to make up one whole iteration of the inner loop
+ *
+ * There are (in general) three distinct code paths, selected between
+ * depending upon how long the pixel row is. If it is long enough that there
+ * is at least one iteration of the inner loop (as described above) then
+ * this is described as the "wide" case. If it is shorter than that, but
+ * there are still enough bytes output that there is at least one 16-byte-
+ * long, 16-byte-aligned write to the destination (the optimum type of
+ * write), then this is the "medium" case. If it is not even this long, then
+ * this is the "narrow" case, and there is no attempt to align writes to
+ * 16-byte boundaries. In the "medium" and "narrow" cases, all the
+ * cachelines containing data from the pixel row are prefetched up-front.

+ * Implementation of pixman_composite_over_8888_0565_asm_neon
+ *
+ * This function takes a8r8g8b8 source buffer, r5g6b5 destination buffer and
+ * performs OVER compositing operation. Function fast_composite_over_8888_0565
+ * from pixman-fast-path.c does the same in C and can be used as a reference.
+ *
+ * First we need to have some NEON assembly code which can do the actual
+ * operation on the pixels and provide it to the template macro.
+ *
+ * Template macro quite conveniently takes care of emitting all the necessary
+ * code for memory reading and writing (including quite tricky cases of
+ * handling unaligned leading/trailing pixels), so we only need to deal with
+ * the data in NEON registers.
+ *
+ * NEON registers allocation in general is recommented to be the following:
+ * v0, v1, v2, v3 - contain loaded source pixel data
+ * v4, v5, v6, v7 - contain loaded destination pixels (if they are needed)
+ * v24, v25, v26, v27 - contain loading mask pixel data (if mask is used)
+ * v28, v29, v30, v31 - place for storing the result (destination pixels)
+ *
+ * As can be seen above, four 64-bit NEON registers are used for keeping
+ * intermediate pixel data and up to 8 pixels can be processed in one step
+ * for 32bpp formats (16 pixels for 16bpp, 32 pixels for 8bpp).
+ *
+ * This particular function uses the following registers allocation:
+ * v0, v1, v2, v3 - contain loaded source pixel data
+ * v4, v5 - contain loaded destination pixels (they are needed)
+ * v28, v29 - place for storing the result (destination pixels)
+ */
+
+/*
+ * Step one. We need to have some code to do some arithmetics on pixel data.
+ * This is implemented as a pair of macros: '*_head' and '*_tail'. When used
+ * back-to-back, they take pixel data from {v0, v1, v2, v3} and {v4, v5},
+ * perform all the needed calculations and write the result to {v28, v29}.
+ * The rationale for having two macros and not just one will be explained
+ * later. In practice, any single monolitic function which does the work can
+ * be split into two parts in any arbitrary way without affecting correctness.
+ *
+ * There is one special trick here too. Common template macro can optionally
+ * make our life a bit easier by doing R, G, B, A color components
+ * deinterleaving for 32bpp pixel formats (and this feature is used in
+ * 'pixman_composite_over_8888_0565_asm_neon' function). So it means that
+ * instead of having 8 packed pixels in {v0, v1, v2, v3} registers, we
+ * actually use v0 register for blue channel (a vector of eight 8-bit
+ * values), v1 register for green, v2 for red and v3 for alpha. This
+ * simple conversion can be also done with a few NEON instructions:
+ *
+ * Packed to planar conversion: // vuzp8 is a wrapper macro
+ * vuzp8 v0, v1
+ * vuzp8 v2, v3
+ * vuzp8 v1, v3
+ * vuzp8 v0, v2
+ *
+ * Planar to packed conversion: // vzip8 is a wrapper macro
+ * vzip8 v0, v2
+ * vzip8 v1, v3
+ * vzip8 v2, v3
+ * vzip8 v0, v1
+ *
+ * But pixel can be loaded directly in planar format using LD4 / b NEON
+ * instruction. It is 1 cycle slower than LD1 / s, so this is not always
+ * desirable, that's why deinterleaving is optional.
+ *
+ * But anyway, here is the code:

+ * OK, now we got almost everything that we need. Using the above two
+ * macros, the work can be done right. But now we want to optimize
+ * it a bit. ARM Cortex-A8 is an in-order core, and benefits really
+ * a lot from good code scheduling and software pipelining.
+ *
+ * Let's construct some code, which will run in the core main loop.
+ * Some pseudo-code of the main loop will look like this:
+ * head
+ * while (...) {
+ * tail
+ * head
+ * }
+ * tail
+ *
+ * It may look a bit weird, but this setup allows to hide instruction
+ * latencies better and also utilize dual-issue capability more
+ * efficiently (make pairs of load-store and ALU instructions).
+ *
+ * So what we need now is a '*_tail_head' macro, which will be used
+ * in the core main loop. A trivial straightforward implementation
+ * of this macro would look like this:
+ *
+ * pixman_composite_over_8888_0565_process_pixblock_tail
+ * st1 {v28.4h, v29.4h}, [DST_W], #32
+ * ld1 {v4.4h, v5.4h}, [DST_R], #16
+ * ld4 {v0.2s, v1.2s, v2.2s, v3.2s}, [SRC], #32
+ * pixman_composite_over_8888_0565_process_pixblock_head
+ * cache_preload 8, 8
+ *
+ * Now it also got some VLD/VST instructions. We simply can't move from
+ * processing one block of pixels to the other one with just arithmetics.
+ * The previously processed data needs to be written to memory and new
+ * data needs to be fetched. Fortunately, this main loop does not deal
+ * with partial leading/trailing pixels and can load/store a full block
+ * of pixels in a bulk. Additionally, destination buffer is already
+ * 16 bytes aligned here (which is good for performance).
+ *
+ * New things here are DST_R, DST_W, SRC and MASK identifiers. These
+ * are the aliases for ARM registers which are used as pointers for
+ * accessing data. We maintain separate pointers for reading and writing
+ * destination buffer (DST_R and DST_W).
+ *
+ * Another new thing is 'cache_preload' macro. It is used for prefetching
+ * data into CPU L2 cache and improve performance when dealing with large
+ * images which are far larger than cache size. It uses one argument
+ * (actually two, but they need to be the same here) - number of pixels
+ * in a block. Looking into 'pixman-arm-neon-asm.h' can provide some
+ * details about this macro. Moreover, if good performance is needed
+ * the code from this macro needs to be copied into '*_tail_head' macro
+ * and mixed with the rest of code for optimal instructions scheduling.
+ * We are actually doing it below.
+ *
+ * Now after all the explanations, here is the optimized code.
+ * Different instruction streams (originaling from '*_head', '*_tail'
+ * and 'cache_preload' macro) use different indentation levels for
+ * better readability. Actually taking the code from one of these
+ * indentation levels and ignoring a few LD/ST instructions would
+ * result in exactly the code from '*_head', '*_tail' or 'cache_preload'
+ * macro!

+ * This macro takes care of:

+ * - doing most of the work related to L2 cache preload
+ * - encourages the use of software pipelining for better instructions
+ * scheduling
+ *
+ * The user of this macro has to provide some configuration parameters

+ * This is a macro for implementing cache preload. The main idea is that
+ * cache preload logic is mostly independent from the rest of pixels
+ * processing code. It starts at the top left pixel and moves forward
+ * across pixels and can jump across scanlines. Prefetch distance is
+ * handled in an 'incremental' way: it starts from 0 and advances to the
+ * optimal distance over time. After reaching optimal prefetch distance,
+ * it is kept constant. There are some checks which prevent prefetching
+ * unneeded pixel lines below the image (but it still can prefetch a bit
+ * more data on the right side of the image - not a big issue and may
+ * be actually helpful when rendering text glyphs). Additional trick is
+ * the use of LDR instruction for prefetch instead of PLD when moving to
+ * the next line, the point is that we have a high chance of getting TLB
+ * miss in this case, and PLD would be useless.
+ *
+ * This sounds like it may introduce a noticeable overhead (when working with
+ * fully cached data). But in reality, due to having a separate pipeline and
+ * instruction queue for NEON unit in ARM Cortex-A8, normal ARM code can
+ * execute simultaneously with NEON and be completely shadowed by it. Thus
+ * we get no performance overhead at all (*). This looks like a very nice
+ * feature of Cortex-A8, if used wisely. We don't have a hardware prefetcher,
+ * but still can implement some rather advanced prefetch logic in software
+ * for almost zero cost!
+ *
+ * (*) The overhead of the prefetcher is visible when running some trivial
+ * pixels processing like simple copy. Anyway, having prefetch is a must
+ * when working with the graphics data.

+ * PDF blend modes:

+ * The following blend modes have been taken from the PDF ISO 32000
+ * specification, which at this point in time is available from
+ *
+ * http://www.adobe.com/devnet/pdf/pdf_reference.html
+ *
+ * The specific documents of interest are the PDF spec itself:
+ *
+ * http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/PDF32000_2008.pdf
+ *
+ * chapters 11.3.5 and 11.3.6 and a later supplement for Adobe Acrobat
+ * 9.1 and Reader 9.1:
+ *
+ * http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/adobe_supplement_iso32000_1.pdf
+ *
+ * that clarifies the specifications for blend modes ColorDodge and
+ * ColorBurn.
+ *
+ * The formula for computing the final pixel color given in 11.3.6 is:
+ *
+ * αr × Cr = (1 – αs) × αb × Cb + (1 – αb) × αs × Cs + αb × αs × B(Cb, Cs)
+ *
+ * with B() is the blend function. When B(Cb, Cs) = Cs, this formula
+ * reduces to the regular OVER operator.
+ *
+ * Cs and Cb are not premultiplied, so in our implementation we instead
+ * use:
+ *
+ * cr = (1 – αs) × cb + (1 – αb) × cs + αb × αs × B (cb/αb, cs/αs)
+ *
+ * where cr, cs, and cb are premultiplied colors, and where the
+ *
+ * αb × αs × B(cb/αb, cs/αs)
+ *
+ * part is first arithmetically simplified under the assumption that αb
+ * and αs are not 0, and then updated to produce a meaningful result when
+ * they are.
+ *
+ * For all the blend mode operators, the alpha channel is given by
+ *
+ * αr = αs + αb + αb × αs

+ * specification, which at this point in time is available from
+ *
+ * http://www.adobe.com/devnet/pdf/pdf_reference.html
+ *
+ * The specific documents of interest are the PDF spec itself:
+ *
+ * http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/PDF32000_2008.pdf

+ * chapters 11.3.5 and 11.3.6 and a later supplement for Adobe Acrobat
+ * 9.1 and Reader 9.1:
+ *
+ * http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/adobe_supplement_iso32000_1.pdf
+ *
+ * that clarifies the specifications for blend modes ColorDodge and
+ * ColorBurn.
+ *
+ * The formula for computing the final pixel color given in 11.3.6 is:
+ *
+ * αr × Cr = (1 – αs) × αb × Cb + (1 – αb) × αs × Cs + αb × αs × B(Cb, Cs)
+ *
+ * with B() is the blend function. When B(Cb, Cs) = Cs, this formula
+ * reduces to the regular OVER operator.
+ *
+ * Cs and Cb are not premultiplied, so in our implementation we instead
+ * use:
+ *
+ * cr = (1 – αs) × cb + (1 – αb) × cs + αb × αs × B (cb/αb, cs/αs)
+ *
+ * where cr, cs, and cb are premultiplied colors, and where the
+ *
+ * αb × αs × B(cb/αb, cs/αs)
+ *
+ * part is first arithmetically simplified under the assumption that αb
+ * and αs are not 0, and then updated to produce a meaningful result when
+ * they are.
+ *
+ * For all the blend mode operators, the alpha channel is given by
+ *
+ * αr = αs + αb + αb × αs

+ * window as the source. It would create a pixman image pointing
+ * to some bogus position in memory, but then set a clip region

+ *
+ * Due to a bug in old versions of pixman, where it would not clip
+ * against the image bounds when a clip region was set, this would
+ * actually work. So when the pixman bug was fixed, a workaround was
+ * added to allow certain out-of-bound accesses. This function disabled

+ * Main loop template for single pass bilinear scaling. It needs to be

+ * The needed function has the following prototype:
+ *
+ * scanline_func (dst_type_t * dst,
+ * const mask_type_ * mask,
+ * const src_type_t * src_top,
+ * const src_type_t * src_bottom,
+ * int32_t width,
+ * int weight_top,
+ * int weight_bottom,
+ * pixman_fixed_t vx,
+ * pixman_fixed_t unit_x,
+ * pixman_fixed_t max_vx,
+ * pixman_bool_t zero_src)
+ *
+ * Where:
+ * dst - destination scanline buffer for storing results
+ * mask - mask buffer (or single value for solid mask)
+ * src_top, src_bottom - two source scanlines
+ * width - number of pixels to process
+ * weight_top - weight of the top row for interpolation
+ * weight_bottom - weight of the bottom row for interpolation
+ * vx - initial position for fetching the first pair of
+ * pixels from the source buffer
+ * unit_x - position increment needed to move to the next pair
+ * of pixels
+ * max_vx - image size as a fixed point value, can be used for
+ * implementing NORMAL repeat (when it is supported)
+ * zero_src - boolean hint variable, which is set to TRUE when
+ * all source pixels are fetched from zero padding
+ * zone for NONE repeat
+ *
+ * Note: normally the sum of 'weight_top' and 'weight_bottom' is equal to
+ * BILINEAR_INTERPOLATION_RANGE, but sometimes it may be less than that
+ * for NONE repeat when handling fuzzy antialiased top or bottom image
+ * edges. Also both top and bottom weight variables are guaranteed to
+ * have value, which is less than BILINEAR_INTERPOLATION_RANGE.
+ * For example, the weights can fit into unsigned byte or be used
+ * with 8-bit SIMD multiplication instructions for 8-bit interpolation
+ * precision.

+ * See section 8.7.4.5.4 Type 3 (Radial) Shadings of the PDF Reference
+ * Manual (PDF 32000-1:2008 at the time of this writing).
+ *
+ * In the radial gradient problem we are given two circles (c₁,r₁) and
+ * (c₂,r₂) that define the gradient itself.
+ *
+ * Mathematically the gradient can be defined as the family of circles
+ *
+ * ((1-t)·c₁ + t·(c₂), (1-t)·r₁ + t·r₂)
+ *
+ * excluding those circles whose radius would be < 0. When a point
+ * belongs to more than one circle, the one with a bigger t is the only
+ * one that contributes to its color. When a point does not belong
+ * to any of the circles, it is transparent black, i.e. RGBA (0, 0, 0, 0).
+ * Further limitations on the range of values for t are imposed when
+ * the gradient is not repeated, namely t must belong to [0,1].
+ *
+ * The graphical result is the same as drawing the valid (radius > 0)
+ * circles with increasing t in [-inf, +inf] (or in [0,1] if the gradient
+ * is not repeated) using SOURCE operator composition.
+ *
+ * It looks like a cone pointing towards the viewer if the ending circle
+ * is smaller than the starting one, a cone pointing inside the page if
+ * the starting circle is the smaller one and like a cylinder if they
+ * have the same radius.
+ *
+ * What we actually do is, given the point whose color we are interested
+ * in, compute the t values for that point, solving for t in:
+ *
+ * length((1-t)·c₁ + t·(c₂) - p) = (1-t)·r₁ + t·r₂
+ *
+ * Let's rewrite it in a simpler way, by defining some auxiliary
+ * variables:
+ *
+ * cd = c₂ - c₁
+ * pd = p - c₁
+ * dr = r₂ - r₁
+ * length(t·cd - pd) = r₁ + t·dr
+ *
+ * which actually means
+ *
+ * hypot(t·cdx - pdx, t·cdy - pdy) = r₁ + t·dr
+ *
+ * or
+ *
+ * ⎷((t·cdx - pdx)² + (t·cdy - pdy)²) = r₁ + t·dr.
+ *
+ * If we impose (as stated earlier) that r₁ + t·dr >= 0, it becomes:
+ *
+ * (t·cdx - pdx)² + (t·cdy - pdy)² = (r₁ + t·dr)²
+ *
+ * where we can actually expand the squares and solve for t:
+ *
+ * t²cdx² - 2t·cdx·pdx + pdx² + t²cdy² - 2t·cdy·pdy + pdy² =
+ * = r₁² + 2·r₁·t·dr + t²·dr²
+ *
+ * (cdx² + cdy² - dr²)t² - 2(cdx·pdx + cdy·pdy + r₁·dr)t +
+ * (pdx² + pdy² - r₁²) = 0
+ *
+ * A = cdx² + cdy² - dr²
+ * B = pdx·cdx + pdy·cdy + r₁·dr
+ * C = pdx² + pdy² - r₁²
+ * At² - 2Bt + C = 0
+ *
+ * The solutions (unless the equation degenerates because of A = 0) are:
+ *
+ * t = (B ± ⎷(B² - A·C)) / A
+ *
+ * The solution we are going to prefer is the bigger one, unless the
+ * radius associated to it is negative (or it falls outside the valid t
+ * range).
+ *
+ * Additional observations (useful for optimizations):
+ * A does not depend on p
+ *
+ * A < 0 <=> one of the two circles completely contains the other one
+ * <=> for every p, the radiuses associated with the two t solutions
+ * have opposite sign

+ * The functions in this file implement the Region abstraction used extensively
+ * throughout the X11 sample server. A Region is simply a set of disjoint
+ * (non-overlapping) rectangles, plus an "extent" rectangle which is the
+ * smallest single rectangle that contains all the non-overlapping rectangles.
+ *
+ * A Region is implemented as a "y-x-banded" array of rectangles. This array
+ * imposes two degrees of order. First, all rectangles are sorted by top side
+ * y coordinate first (y1), and then by left side x coordinate (x1).
+ *
+ * Furthermore, the rectangles are grouped into "bands". Each rectangle in a
+ * band has the same top y coordinate (y1), and each has the same bottom y
+ * coordinate (y2). Thus all rectangles in a band differ only in their left
+ * and right side (x1 and x2). Bands are implicit in the array of rectangles:
+ * there is no separate list of band start pointers.
+ *
+ * The y-x band representation does not minimize rectangles. In particular,
+ * if a rectangle vertically crosses a band (the rectangle has scanlines in
+ * the y1 to y2 area spanned by the band), then the rectangle may be broken
+ * down into two or more smaller rectangles stacked one atop the other.
+ *
+ * ----------- -----------
+ * | | | | band 0
+ * | | -------- ----------- --------
+ * | | | | in y-x banded | | | | band 1
+ * | | | | form is | | | |
+ * ----------- | | ----------- --------
+ * | | | | band 2
+ * -------- --------
+ *
+ * An added constraint on the rectangles is that they must cover as much
+ * horizontal area as possible: no two rectangles within a band are allowed
+ * to touch.
+ *
+ * Whenever possible, bands will be merged together to cover a greater vertical
+ * distance (and thus reduce the number of rectangles). Two bands can be merged
+ * only if the bottom of one touches the top of the other and they have
+ * rectangles in the same places (of the same width, of course).
+ *
+ * Adam de Boor wrote most of the original region code. Joel McCormack
+ * substantially modified or rewrote most of the core arithmetic routines, and
+ * added pixman_region_validate in order to support several speed improvements
+ * to pixman_region_validate_tree. Bob Scheifler changed the representation
+ * to be more compact when empty or a single rectangle, and did a bunch of
+ * gratuitous reformatting. Carl Worth did further gratuitous reformatting
+ * while re-merging the server and client region code into libpixregion.
+ * Soren Sandmann did even more gratuitous reformatting.

+ * window as the source. It would create a pixman image pointing
+ * to some bogus position in memory, but then set a clip region
+ * to the position where the actual bits were.
+ *
+ * Due to a bug in old versions of pixman, where it would not clip
+ * against the image bounds when a clip region was set, this would
+ * actually work. So when the pixman bug was fixed, a workaround was
+ * added to allow certain out-of-bound accesses. This function disabled
+ * those workarounds.
+ *
+ * Since 0.21.2, pixman doesn't do these workarounds anymore, so now this
+ * function is a no-op.
