f7f82d773b the TrueType glyph loader is now much more paranoid, this avoids
unpleasant overwrites in the case of invalid glyph data (found in
the output of buggy font converters)

the computation of auto-hinted stem widths has been modified to
avoid certain color fringes in LCD-decimation rendering (a.k.a.
"ClearType")

662b344c23 * src/type1/t1objs.c (T1_Face_Init): fixed a bug that crashed the
library when dealing with certain weird fonts (like "Stalingrad",
        in "sadn.pfb". This font has no full font name entry.. )

        * src/base/ftoutln.c, include/freetype/ftoutln.h: added the
        FT_Outline_Check API to check the consistency of outline data

        * src/base/ftobjs.c (FT_Load_Glyph): added a call to the new
        FT_Outline_Check to ensure that loaded glyphs are valid. This
        allows certain fonts like "tt1095m_.ttf" to be loaded even though
        it appears they contain really funky glyphs..

        there still is a bug there though.. !!

4937a3ebd2 * src/truetype/ttgload.c (TT_Load_Glyph), src/base/ftobjs.c
(FT_Load_Glyph): "fixed" the bug that prevented embedded bitmaps from
        begin loaded when the auto-hinter is used.. This actually is a hack
        but will be enough until the internal re-design scheduled for
        FreeType 2.1

c40a7e2d50 * include/freetype/cache/ftcache.h: added comments to indicate that
some of the exported functions should only be used by applications
        that need to implement custom cache types

        * src/truetype/ttgload.c: fixed a nasty bug that prevent composites
        from loading correctly. Believe it or not, this was due to an invalid
        macro definition !!

ac6cc419df modified the TrueType interpreter to let it
use the new trigonometric functions provided in "fttrigon.h". This
        gets rid of some old 64-bit computation routines, as well as many
        warnings when compiling the library with the "long long" 64-bit
        integer type.

f96594faf0 integrated Yamano-Uchi changes to the base source code. However,
I've made a few modifications:

  - there is no new field named "driver" in "FT_SizeRec"

  - the new fields in "TT_SizeRec" are:

       strike_index   :: value 0xFFFF means "no sbit strike selected"
       strike_metrics :: the FT_Size_Metrics structure corresponding to
                         the currently selected strike

  - the code in "ttload.c" has been somewhat cleaned up too

thanks a lot, Y-U !!
