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

        src/type1/t1gload.c:

          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%.

David Turner 5b5f382b7d * src/autofit/aflatin.c, src/autofit/afhints.c: changed the
implementation of the LIGHT hinting mode to completely disable

        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.

David Turner e664efaddd * src/autofit/*: important fixes to the auto-fitter. The output
now seems to be 100% equivalent to the auto-hinter, while being
        about 2% faster (which proves that script-specific algorithm
        selection isn't a performance problem).

        to test it, change "autohint" to "autofit" in
        <freetype/config/ftmodule.h> and recompile.

        a few more testing is needed before making this the official
        auto-hinting module
