Many casts and slight argument type changes to make it work with
a 16bit compiler.
[TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Call

first version was kind of a hack; the current implementation of the
procedure to extract the required symbols is much cleaner.
Reworked creation of MMS files, avoiding a number of temporary files
which were created in the previous version.
Further work on creating descrip.mms files on the fly.
* builds/vms/descrip.mms, src/autohint/descrip.mms,
src/type1/descrip.mms: Removed.

boundary whenever possible.

m's maintain their symmetry.

open_face_from_buffer, Mac_Read_POST_Resource,
Mac_Read_sfnt_Resource, IsMacResource, IsMacBinary, load_mac_face)
[!FT_MACINTOSH]: New functions.
(FT_Open_Face) [!FT_MACINTOSH]: Use load_mac_face.
* src/base/ftobjs.c (FT_Load_Glyph): Scale linear advance width only
if FT_FACE_FLAG_SCALABLE is set (otherwise we have a division by
zero since FNT and friends don't define `face->units_per_EM').
`switch' statement to make it run faster.
(ah_outline_compute_segments): Reset `segment->score' and
`segment->link'.
(ah_outline_link_segments): Provide alternative code which does
the same but runs much faster.
Handle major direction also.

similar to the PCF driver.
* src/bdf/bdf.h (_hashnode): Use `const' for `key'.
Updated.
* src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask'
is declared twice. It is perhaps better to modify the zlip source
files directly instead of this hack.
(zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts
to make build with g++ successful.
* README.UNX: removed (now replaced by docs/INSTALL.UNX)
* src/pshinter/pshalgo3.c: the hinter now performs as in 2.1.3 and
will ignore stem quantization only when FT_LOAD_TARGET_SMOOTH is used
* src/base/ftobjs.c: changed the default computations to include rounding
in all cases, this is required to provide accurate kerning data when
native TrueType hinting is enabled.

according to the Postscript spec (the previous one was too restrictive)
src/autohint/ahhint.c: fixed blue-scale problem

in rare circumstances (mostly with broken fonts)
* include/freetype/internal/ftobjs.h, src/base/ftobjs.c, src/bdf/bdfdrivr.c,
src/pcf/pcfdriver.c, src/pfr/pfrsbit.c, src/sfnt/ttsbit.c,
src/type42/t42objs.c, src/winfonts/winfnt.c: introduced three new functions
to deal with glyph bitmaps within FT_GlyphSlot objects. these are:
ft_glyphslot_free_bitmap
ft_glyphslot_alloc_bitmap
ft_glyphslot_set_bitmap
these are much more convenient to use than managing the FT_GLYPH_OWN_BITMAP
flag manually. the font drivers have been modified to use them as well.
* src/cache/ftlru.c: fixed an invalid assertion check
to control memory debugging with FreeType. See the description of
"FT2_DEBUG_MEMORY", "FT2_ALLOC_TOTAL_MAX" and "FT2_ALLOC_COUNT_MAX"
in DEBUG.TXT
* src/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcsbits.c,
ftlru.c: fixed the cache sub-system to correctly deal with out-of-memory
conditions.
* src/pfr/pfrobjs.c, src/pfr/pfrsbits.c: fixing compiler warnings and a
small memory leak
* src/psaux/psobjs.c (t1_reallocate_table): fixed a bug (memory leak) that
only happened when trying to resize an array would end in an OOM.
* src/smooth/ftgrays.c: removed compiler warnings / volatile bug
* src/truetype/ttobjs.c: removed segmentation fault that happened in
tight memory environments.
when available in Asian fonts

comments
* src/truetype/ttdriver.c (Set_Char_Sizes): fixed a rounding bug when
computing the scale factors for a given character size in points with
resolution.
when trying to read certain compressed gzip files. The following test
could be used to reveal the bug:
touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz
* src/pfr/pfrobjs.c, src/pfr/pfrload.c, src/pfr/pfrtypes.h: several
fixes to the PFR font driver:
- the list of available embedded bitmaps was not correctly set
in the root FT_FaceRec structure describing the face
- the glyph loader always tried to load the outlines when
FT_LOAD_SBITS_ONLY was specified
- the table loaded now scans for *undocumented* elements of a
physical font's auxiliary data record, this is necessary to
retrieve the "real" family and style names.
NOTE THAT THIS CHANGES THE FAMILY NAME OF MANY PFR FONTS !!
src/base/ftbdf.c, src/bdf/bdfdrivr.c, src/pcf/pcfdrivr.c,
src/pcf/pcfread.h:
adding a new API, named FT_Get_BDF_Property to retrieve the BDF
properties of a given PCF or BDF font
--copy' from libtool 1.4.3.
* builds/unix/aclocal.m4: Regenerated with `aclocal -I .' from
automake 1.7.1.
* builds/unix/configure: Regenerated with autoconf 2.54.
* builds/unix/config.guess, builds/unix/config.sub: Updated from
`config' CVS module at subversions.gnu.org.
* builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from
`automake' CVS module at subversions.gnu.org.
include/freetype/ftwinfnt.h, src/base/winfnt.c, src/winfonts/winfnt.c,
src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms:
added a Windows .FNT specific API (mostly for Wine). Also fixed a nasty
bug in the header loader which would cause invalid memory overwrites
* include/freetype/config/ftoption.h, src/autohint/ahglobal.h,
src/autohint/ahglobal.c, src/autohint/ahglyph.c,
src/autohint/ahtypes.h:
included David Chester's patches to the auto-hinter in order to
slightly improve the output. Note that everything is controlled
through the new FT_CONFIG_OPTION_CHESTER_HINTS defined at the
end of "ftoption.h", there are also individual FT_CONFIG_CHESTER_XXX
macros to control individual "features".
Note that all improvements are enabled by default, but can be
tweaked for optimization and testing purpose. The configuration
macros will most likely disappear in the short future.
2003-01-11 David Turner <david@freetype.org>
* include/freetype/internal/fnttypes.h: fixed a structure field
definition to avoid memory overwrites
the API is likely to change however.

invalid values for large negative angle differences (resulting in
incorrect stroker computations, among other things)

assertion, and changing code to avoid hash table size contraction

the three version numbers being used on Unix, as well as provide the AutoConf
fragment provided by Lars Clausen

prevented bezier arcs with negative vertical coordinates to be rendered
appropriately
2002-11-27 Vincent Caron <v.caron@zerodeux.net>
* builds/unix/unix-def.in, builds/unix/freetype-config.in,
builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c:
adding support for system zlib installations when available on the
target platform (Unix only)
Now it loads UCS-4 charmaps when there is one.
* src/base/ftobjs.c (find_unicode_charmap): new function.
* src/base/ftobjs.c (open_face): refer to the above one.
* src/base/ftobjs.c (FT_Select_Charmap): idem.
