Points which are very near to each other are now marked as such.
The `weak' flag is then computed by using the `in' vector of the
first and the `out' vector of the last point of a group of near
points.
For example, this fixes the rendering of glyph `Oslash' in
`Roboto-Thin.ttf'.
* src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'.
* src/autofit/afhints.c (af_glyph_hints_reload): Introduce
the heuristic value `near_limit' to decide whether the current point
is near to the previous one, then set `AF_FLAG_NEAR' accordingly.
Store good `in' vector (of last non-near point) in
`last_good_in_{x,y}' and use it as an argument to
`ft_corner_is_flat' if necessary.
This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.
To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code. Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.
Suggested by Graham.
* src/autofit/afhints.c (af_glyph_hints_compute_inflections):
Removed.
(af_glyph_hints_reload): Remove third argument.
Update all callers.

* include/freetype/ftxf86.h: Fix and extend comment so that it
appears in the documentation.
* include/freetype/ftchapters.h: Add `font_format' section.

this is a major patch used to drastically improve the performance
of loading glyphs. This both speeds up loading the glypn vector
themselves and the auto-fitter.
note that we've started using inline assembler with GCC to
implement FT_MulFix, given that this function is so damn
important for the engine's performance.
the resulting speed-up is about 25%.
src/autofit/aftypes.h, src/autofit/afloader.c, src/autofit/autofit.c:
adding experimental implementation of "warp hinting" (new hinting
algorithm for gray-level and LCD rendering). It is disabled by default,
you need to #define AF_USE_WARPER in aftypes.h to enable it.
implementation of the LIGHT hinting mode to completely disable
horizontal hinting. This is an experimental effort to integrate
David Chester's latest patch without fucking the other hinting
modes as well.
Note that this doesn't force auto-hinting for all fonts however.
- fixing apinames.c, adding support for Watcom and Borland compilers
- adding generation of exported symbols list to the build system, including the Unix one !!
