Behdad Esfahbod 5163425344 [base] Don't allocate `library->raster_pool' anymore.
It's unused after the following commits:

  [raster] Allocate render pool for mono rasterizer on the stack.
  [raster] Remove 5-level gray AA mode from monochrome rasterizer.

The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
serve, which is, to adjust the pool size.  But the pool is now
allocated on the stack on demand.

Werner Lemberg 1924134710 Introduce `coverages'.
Coverages are the interface to the HarfBuzz library to access
OpenType features for handling glyphs not addressable by the cmap.

Right now, compilation of HarfBuzz is only added to the development
build.  A solution for standard build mode will be delayed until
HarfBuzz gets split into two libraries to avoid mutual dependencies
between FreeType and HarfBuzz.

Note that this is only a first step in handling coverages, basically
providing the framework only.  Code for handling selected OpenType
features (this is, actually using the data in `afcover.h') will
follow.

* devel/ftoption.h, include/config/ftoption.h
(FT_CONFIG_OPTION_USE_HARFBUZZ): New macro.

* src/autofit/hbshim.c, src/autofit/hbshim.h, src/autofit/afcover.h:

Werner Lemberg fae3820764 Simplify header file hierarchy.
This large patch changes the header file directory layout from
`include/freetype/...' to `include/...', effectively removing one
level.  Since the file `ft2build.h' is also located in `include'
(and it stays there even after installation), all FreeType header
files are now in a single directory.

Applications that use (a) `freetype-config' or FreeType's
`pkg-config' file to get the include directory for the compiler, and
(b) the documented way for header inclusion like

  #include <ft2build.h>
  #include FT_FREETYPE_H
  ...

don't need any change to the source code.

* include/freetype/*: Move up to...
* include/*: ... this directory.

* builds/amiga/include/freetype/*: Move up to...
* builds/amiga/include/*: ... this directory.

*/*: Essentially do `s@/freetype/@/@' where appropriate.

* CMakeList.txt: Simplify.
* builds/unix/freetype-config.in, builds/unix/freetype2.in: For
`--cflags', return a single directory.
* builds/unix/install.mk (install): No longer try to remove `cache'
and `internal' subdirectories; instead, remove the `freetype'
subdirectory.

Behdad Esfahbod 760d342d37 Add support for color embedded bitmaps (eg. color emoji).
A new load flag, FT_LOAD_COLOR, makes FreeType load color
embedded-bitmaps, following this draft specification

  https://color-emoji.googlecode.com/git/specification/v1.html

which defines two new SFNT tables, `CBDT' and `CBLC' (named and
modeled after `EBDT' and `EBLC', respectively).  The color bitmaps
are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
pre-multiplied sRGB images.  If PNG support is available, PNG color
images as defined in the same proposed specification are supported
also.

Note that color bitmaps are converted to grayscale if client didn't
ask for color.

Infinality 79e36baebb [truetype] Support subpixel hinting.
This is the large, famous `Infinality' patch to support ClearType
bytecode which has been available from
http://www.infinality.net/blog/ for some time, and which has been
refined over the last years.  While still experimental, it is now
mature enough to be included directly into FreeType.

Most of the code is based on the ClearType whitepaper written by
Greg Hitchcock

  http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx

which gives a detailed overview of the necessary changes to the
Microsoft rasterizer so that older fonts are supported.  However, a
lot of details are still missing, and this patches provides a
framework to easily handle rendering issues down to the glyph level
of certain fonts.

Note that ClearType support is not completely implemented!  In
particular, full support for the options `compatible_widths',
`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
instruction) is missing.

* src/truetype/ttsubpix.c: New file, providing code to handle
`tweaks', this is, rules for certain glyphs in certain fonts
(including wildcards) which need a special treatment.

* src/truetype/ttsubpix.h: New file, holding the tweaking rules.

David Turner e3d6e94853 CHANGES BETWEEN 2.2.1 and 2.2.2
I. IMPORTANT BUG FIXES

    - Various integer overflows have been fixed.

    - PFB fonts with MacOS resource fork weren't  handled correctly on
      non-MacOS platforms.

    - The PCF font loarder has been seriously hardened against malformed
      font files.

  II. IMPORTANT CHANGES

    - the unpatented hinter is now part of the default build of the
      library, and we added code to automatically support "tricky"
      fonts that need it.

      what this means is that FreeType should "just work" with certain
      Asian fonts, like MingLiu, which cannot properly load without a
      bytecode interpreter, but fortunately do not use any of the
      patented bytecode opcodes.

      Note that the API didn't change, so you can still force
      unpatented hinting with a special parameter to FT_Open_Face
      as well.

      if you're an embedded systems developer, you might want to
      *disable* the feature to save code space by undefining
      TT_CONFIG_OPTION_UNPATENTED_HINTING in ftoption.h.

    - LCD-optimized rendering is now disabled in all default builds
      of the library, mainly due to patent reasons. For more information
      see:

      http://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html

      a new configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING has
      been introduced in ftoption.h; manually define it in this file
      if you want to re-enable the feature.

      the change only affects the implementation, not the FreeType API.
      This means that clients don't need to be modified, because the
      library still generates LCD decimated bitmaps, but with the added
      constraint that R=G=B on each triplet.

   - Some computation bugs in the TrueType bytecode interpreter were found,
     which allow us to get rid of very subtle and rare differences we had
     with the Windows renderer.

  III. MISCELLANEOUS

    - TrueType glyph loading is now about 25% faster.

    - the anti-aliased rasterizer has been optimized and is now 15% to 25%
      percent faster than the previous one, depending on content

    - the Type 1 loader has been improved; as an example, it now skips
      over top-level dictionaries properly
