(CFLAGS): Don't include @CPPFLAGS@.
* builds/freetype.mk (FT_CFLAGS): Add CPPFLAGS.
- fixing apinames.c, adding support for Watcom and Borland compilers
- adding generation of exported symbols list to the build system, including the Unix one !!
sorry Werner, I have no time to document this in ChangeLog at the moment
* src/lzw/ftlzw2.c, src/lzw/ftzopen.h, src/lzw/ftzopen.c, src/lzw/rules.mk:
first version of LZW loader re-implementation. Apparently, saves about
260 KB of heap memory when loading tir24.pcf.Z
FT_New_Size if we're opening a face with face_index < 0 (which is only
used for testing the format).
* src/gxvalid/gxvmort0.c: removed compiler warning
removing compiler warnings (Visual C++ /W4)
* Jamfile, src/otvalid/{otvcommn.h,otvgdef.c,otvgpos.c,otvgsub.c,
otvjstf.c}: modified the code to use a different pre-processor trick
to implement the OTV_NEST1, OTV_NEST2 and OTV_NEST3 macros. The code
now compiles neatly with Visual C++. The 'otvalid' module has been
put in the Jamfile build again.
ft_glyphslot_grid_fit_metrics.
* src/truetype/ttgload.c (compute_glyph_metrics): Use
ft_glyphslot_grid_fit_metrics.
* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
(cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Use
ft_glyphslot_grid_fit_metrics.
FT_Outline_Get_CBox is called twice.
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Modify metrics to more
reasonable values when emboldening outline glyphs. The theoretic
ones are unrealistic.

strength.
Don't increase slot->advance.y.
* include/freetype/freetype.h (FREETYPE_MINOR): Set to 2.

builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj: s/219/2110/, s/2.1.9/2.1.10/.

s/2.1.9/2.1.10/.
* docs/CHANGES, docs/VERSION.DLL: Updated.

The next release will be 2.2.0, so don't worry about source code
backwards compatibility.

vertBearingY to make glyphs centered vertically.
Fix some bugs in vertical metrics:
. loader->pp3.y and loader->pp4.y are in 26.6 format, not in font
units.
. As we use the glyph's cbox to calculate the top bearing now
there iss no need to adjust `top'.
* src/otvalid/otvcommn.h (OTV_OPTIONAL_TABLE): Use FT_UShort to be
in sync with OTV_OPTIONAL_OFFSET. Reported by YAMATO Masatake.

FT_Bitmap_Embolden.
(CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove
-fno-strict-aliasing.
Say you have `(Foo*)x' and want to assign, pass, or return it as
`(Bar*)'. If you simply say `x' or `(Bar*)x', then the C compiler
would warn you that type casting incompatible pointer types breaks
strict-aliasing. The solution is to cast to `(void*)' instead which
is the generic pointer type, so the compiler knows that it should
make no strict-aliasing assumption on `x'. But the problem with
`(void*)x' is that seems like in C++, unlike C, `void*' is not a
generic pointer type and assigning `void*' to `Bar*' without a cast
causes an error. The solution is to cast to `Bar*' too, with
`(Bar*)(void*)x' as the result -- this is what the patch does.
* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP),

before any test).
