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.
This is based on code written by Lifter
<http://unixforum.org/index.php?showuser=11691>. It fixes
FreeDesktop bug #27386.
* src/base/ftlcdfil.c (FT_Library_SetLcdFilterWeights): New
function.
* include/freetype/ftlcdfil.h: Updated.
* docs/CHANGES: Updated.
and FT_FORCE_LEGACY_LCD_FILTER at compile time. Define these macros
when building the library to change the default LCD filter to be
used. This is only useful for experimentation
src/base/ftlcdfilt.c, src/smooth/ftsmooth.c: API change for
the LCD filter, the FT_LcdFilter value is a enum describing
which filter to apply, new values FT_LCD_FILTER_LIGHT and
FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
algorithm which produces incredible color fringes for everything
except very-well hinted text)
* src/autofit/aflatin.c: various tiny improvements that drastically
improve the handling of serif fonts and of LCD/LCD_V hinting modes.
