[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.

Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.

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. (af_property_get, af_autofitter_init): Updated. * src/autofit/afpic.c: Update use of `SCRIPT' and `STYLE' macros. * src/autofit/afranges.h: Update use of `SCRIPT' macro. * src/autofit/autofit.c [FT_CONFIG_OPTION_USE_HARFBUZZ]: Include `hbshim.c'. * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `hbshim.c'.

[autofit] Allocate AF_Loader on the stack instead of AF_Module. Stop sharing a global `AF_Loader'. Allocate one on the stack during glyph load. Right now this results in about 25% slowdown, to be fixed in a following commit. With this patch loading glyphs from different faces from different threads doesn't immediately crash in the autohinting loader code. Bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1164941 * src/autofit/afloader.c (af_loader_init): Pass `AF_Loader' and `FT_Memory' instead of `AF_Module' as arguments. (af_loader_reset, af_loader_load_glyph): Also pass `loader' as argument. (af_loader_done): Use `AF_Loader' instead of `AF_Module' as argument. * src/autofit/afmodule.c (af_autofitter_init): Don't call `af_loader_init'. (af_autofitter_done): Don't call `af_loader_done'. (af_autofitter_load_glyph): Use a local `AF_Loader' object. * src/autofit/afloader.h: Include `afmodule.h'. Update prototypes. Move typedef for `AF_Module' to... * src/autofit/afmodule.h: ... this place. No longer include `afloader.h'.
