Werner Lemberg 9ac9060df0 [GSoC] src/*.*: Convert block comments to `light' style.
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.

No change in functionality, of course.

I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
https://github.com/nikramakrishnan/freetype-docs.git.

Werner Lemberg 37412ff9f4 Don't use macro names that contain `__' [1/2].
Such macro names are reserved for both C and C++.

Werner Lemberg a336400112 [autofit] Introduce two more slots for standard characters.

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:
New files.

* src/autofit/afscript.h: Add HarfBuzz script name tags.

* src/autofit/afstyles.h: Add default coverage enumeration values.

* src/autofit/aftypes.h: Update use of `SCRIPT' and `STYLE' macros.
(AF_Coverage): New enumeration (generated by `afcover.h').
(AF_StyleClassRec): New member `coverage'.
(AF_DEFINE_STYLE_CLASS): Updated.

* include/internal/fttrace.h: Add `afharfbuzz' for tracing coverage
data.

* src/autofit/afglobal.h: Update use of `SCRIPT' and `STYLE' macros.
(AF_SCRIPT_FALLBACK): Renamed to ...
(AF_STYLE_FALLBACK): ... this.

* src/autofit/afglobal.c: Include `hbshim.c'.
Update use of `SCRIPT' and `STYLE' macros.
(af_face_globals_compute_style_coverage)
[FT_CONFIG_OPTION_USE_HARFBUZZ]: Call `af_get_coverage'.
Update.

* src/autofit/afmodule.h (AF_ModuleRec):
s/fallback_script/fallback_style/.

* src/autofit/afmodule.c (af_property_set): Adapt handling of
`fallback-script' property to set a fallback style.

all libraries needed by FreeType.
