src/autohint/ahhint.c: fixed blue-scale problem
* src/cache/ftccache.c: fixed small bug that could crash the cache
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
* src/sfnt/ttload.c, src/base/ftobjs.c: changed "asian" to "Asian" in
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.
* src/base/fttrigon.c (FT_Angle_Diff): fixing function, it returned
invalid values for large negative angle differences (resulting in
incorrect stroker computations, among other things)
* src/cache/ftccache.c (ftc_node_unlink): removing incorrect
assertion, and changing code to avoid hash table size contraction
* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms:
adding "ftstroker.obj" to default build, as optional component
src/gzip/inftrees.c, src/gzip/zconf.h, src/gzip/zlib.h,
src/gzip/zutil.h: updates to allow compilation without compiler
warnings with LCC-Win32
* include/freetype/freetype.h, docs/VERSION.DLL,
builds/unix/configure.ac: updates for the upcoming 2.1.4 release
src/gzip/inftrees.c, src/gzip/zconf.h, src/gzip/zlib.h,
src/gzip/zutil.h: updates to allow compilation without compiler
warnings with LCC-Win32
* include/freetype/freetype.h, docs/VERSION.DLL,
builds/unix/configure.ac: updates for the upcoming 2.1.4 release
better explain what's happening there
* src/base/ftobjs.c (open_face): included Graham Asher's fix to
prevent faces without Unicode charmaps from loading
* docs/VERSION.DLL: updating document to better explain the differences between
the three version numbers being used on Unix, as well as provide the AutoConf
fragment provided by Lars Clausen
* src/smooth/ftgrays.c (gray_render_conic): fixed small bug that
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.
accept pre-defined charsets, even when the font contains fewer glyphs.
also enforced more checks to ensure that we never overflow the
character codes array in the encoding.
src/otlayout/otlgsub.c, src/otlayout/otlgsub.h, src/otlayout/otlparse.c,
src/otlayout/otlparse.h, src/otlayout/otlutils.h:
updating the OpenType Layout code, adding support fot the first
GSUB lookups. Nothing that really compiles for now though
* src/autohint/ahhint.c: disabled serif stem width quantization. It
produces slightly better shapes though this is not distinguishable
with many fonts.
* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added
support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
the use of system-wide zlib.
Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER,
is not #undef-ed anymore. This allows the build system to define them
depending on the configuration (typically by adding -D flags at
compile time).
* src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings
in optimized mode relative to the "volatile" local variables. This was
not a compiler bug after all, but the fact that a pointer to a volatile
variable is not the same than a volatile pointer to a variable :-)
the fix was to change "volatile FT_Byte* p"
into "FT_Byte* volatile p"
* src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed
compiler warnings in optimized modes
* src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting
any zlib function names outside of the component. This prevents linking
problems on some platforms, when applications want to link FreeType
_and_ ZLib together.
2002-11-05 Juliusz <jch@pps.jussieu.fr>
* src/psaux/psobjs.c (ps_table_add): modified increment loop in
order to implement exponential behaviour
src/pfr/pfrgload.c, src/pfr/pfrobjs.c, src/pfr/pfrtypes.h,
Jamfile, src/base/ftobjs.c: adding support for embedded bitmaps to
the PFR driver, and rewriting its kerning loader / handler to use all
kerning pairs in a physical font (and not just the first item).
* src/tools/docmaker/content.py, src/tools/docmaker/sources.py,
src/tools/docmaker/tohtml.py: fixing a few nasty bugs
* src/sfnt/ttcmap0.c: the validator for format 4 sub-tables is
now capable of dealing with invalid "length" fields at the start
of the sub-table. This allows fonts like "mg______.ttf" (i.e.
Marriage) to return accurate charmaps.

this produces much better anti-aliased text
2002-09-25 Anthony Fok <anthony@thizlinux.com>
* src/sfnt/ttcmap0.c: added support for opens___.ttf (it contains
a charmap that uses offset=0xFFFFU instead of 0x0000 to indicate a
missing glyph)
* src/autohint/ahglobal.c (sort_values): Use FT_Pos for `swap'.
(ah_hinter_compute_widths): Use FT_Pos for `dist'.
Use AH_MAX_WIDTHS.

for `delta'.
(ah_outline_compute_edges): Replace some ints with FT_Int and
FT_Pos.

to FT_Pos.
include/freetype/ftstroker.h, include/freetype/ftsysio.h,
include/freetype/ftsysmem.h, include/freetype/ttnameid.h:
updating the in-source documentation
* src/tools/docmaker/tohtml.py: updating the HTML formatter in the
DocMaker tool
* src/tools/docmaker.py: removing obsolete file
* src/type1/t1parse.h (T1_ParserRec): Change type of `base_len'
and `private_len' to FT_Long.
* src/type1/t1parse.c (T1_Get_Private_Dict): Remove cast for
`private_len'.

Use FT_PtrDist where appropriate.
(parse_encoding): Use FT_Long for `count' and `n'.
(read_binary_data): Use FT_Long* for second parameter.
* src/type1/t1afm.c (afm_atoindex): Use FT_PtrDist.
* src/cache/ftcsbits.c (ftc_sbit_node_load): Remove unused label.
* src/pshinter/pshalgo3.c (psh3_hint_align): Remove unused variable.
debug mode of template instantiation
* src/cff/cffparse.c: fixed the CFF table loader. It didn't accept
empty arrays, and this prevented the loading of certain fonts.
* src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.c: adding fix to
prevent seg fault when hints are provided in an empty glyph !!
* include/freetype/ftimage.h: removed incorrect "zft_" definitions
and updated constants documentation comments
* include/freetype/freetype.h (FT_FaceRec): updating documentation
comment. The "descender" value is always *negative*, not positive !
include/freetype/config/ftmodule.h: updated to correctly support
sub-pixel rendering
* include/freetype/cache/ftcimage.h, include/freetype/cache/ftcsbits.h,
src/cache/ftcimage.c, src/cache/ftcsbit.c: updated to support sub-pixel
rendering correctly. Definition of FTC_ImageTypeRec that replaces the
obsolete FTC_ImageDesc, and has slightly different fields. The
image type is now determined directly by "load_flags" values.
* src/autohint/ahtypes.h, src/autohint/ahhint.c,
src/pshinter/pshalgo3.c, src/pshinter/pshalgo3.h: various enhancements
to the automatic and Postscript hinters !! and sub-pixel hinting now
works correctly (see demo programs)
ft_encoding_symbol to be FT_ENCODING_MS_SYMBOL (instead of
the erroneous FT_ENCODING_SYMBOL)
* builds/unix/unix-def.in: added "datadir" definition
(thanks to Anthony Fok)
to slightly increase the contrast of smooth hinting. This is very similar
to what the auto-hinter does when it comes to stem width computations.
However, it produces better results with well-hinted fonts..
want to list them all here. The operations performed were all logical
transformations of the sources:
- trying to convert all enums and constants to CAPITALIZED_STYLE, with
#define definitions like
#define my_old_constants MY_NEW_CONSTANT
- big, big update of the documentation comments
* include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
include/freetype/ftimage.h: adding support for LCD-optimized rendering
though the new constants/enums:
FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V
this is still work in progress, don't expect everything to work correctly
though most of the features have been implemented.
* adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
targets:
FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
FT_LOAD_TARGET_MONO :: monochrome bitmaps
FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering
FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering
note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
behaviour of the font engine is _unchanged_.
of the "load_flags" parameter of FT_Load_Glyph and FT_Load_Char from
"FT_Int" to "FT_Int32", this in order to support more options.
this should only break binary and/or source compatibility on
16-bit platforms (Atari?)
the SFNT loader to check for SFNT-based font files differently. We now
ignore the range "helper" fields and check the "head" table's magic
number instead.
src/psaux/psobjs.c, src/type1/t1load.c, src/type1/t1tokens.h:
fixing a bug in the Type 1 loader that prevented valid font bounding
boxes to be loaded from multiple master fonts.
to support charmaps for CFF fonts
* src/cff/cffload.c, src/cff/cffload.h, src/cff/cffobjs.c,
src/cff/cffobjs.h, src/cff/cffparse.c, src/cffparse.h, src/cff/cffgload.c,
src/cff/cffgload.h: adding support for CFF charmaps, reformatting the
sources, and removing some bugs in the Encoding and Charset loaders
* src/base/ftdebug.c (ft_debug_init), builds/win32/ftdebug.c
(ft_debug_init), builds/amiga/src/ftdebug.c (ft_debug_init): changed the
syntax of the FT2_DEBUG environment variable used to control debugging
output (i.e. logging and error messages). It must now look like:
any:6 memory:4 io:3 or
any:6,memory:4,io:3 or
any:6;memory:4;io:3
freetype/internal/ftobjs.h, freetype/internal/psaux.h,

src/pshinter/pshalgo2.h, src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.h,
src/pshinter/pshalgo3.c: Adding support for hinter-specific bit flags,
and the new FT_Set_Hint_Flags high-level API
incorrect advances when the outline resolution was different from the
metrics resolution
* src/autohint/ahhint.c: removing compiler warnings
* src/autohint/ahglyph.c: slight improvements to the serif detection
code. More work is needed though..
* src/autohint/ahglobal.c, src/autohint/ahtypes.h, src/autohint/ahhint.c:
small improvements to the automatic hinter. un-even stem-widths have now
disappeared and everything looks much better, even if there are still
issues with serifed fonts.
(t1_face_check_cast): Removed.
(FT_Get_PS_Font_Info): Make it work with CID and Type 42 drivers
also.
* src/type42/t42parse.c (t42_parse_sfnts): Fix compiler warning.
t1_cmap_custom_char_next): Fix index computation -- indices start
with 0 and not with cmap->first.
Provide default charmaps.
* src/bdf/bdfdrivr.c (BDF_Face_Init), src/pcf/pcfdriver.c
(PCF_Face_Init), src/pfr/pfrobjs.c (pfr_face_init),
src/type1/t1objs (T1_Face_Init), src/winfonts/winfnt.c
(FNT_Face_Init): Implement it.
* builds/unix/install.mk (install, uninstall): Handle it.
Fix glyph indices for PFR driver.
* src/pfr/pfrcmap.c (pfr_cmap_char_index, pfr_cmap_char_next):
Increase return value by 1.
* src/pfr/pfrobjs.c (pfr_slot_load): Decrease index by 1.
* src/bdf/bdfdrivr.c (bdf_cmap_init): Don't decrease
cmap->num_encodings.
(bdf_cmap_char_index, bdf_cmap_char_next, BDF_Get_Char_Index):
Increase result by 1 for normal cases.
(BDF_Glyph_Load): Decrease index by 1.
* src/pcf/pcfdriver.c (pcf_cmap_char_index, pcf_cmap_char_next,
PCF_Char_Get_Index): Increase result by 1 for normal cases.
(PCF_Glyph_Load): Decrease index by 1.
* src/pcf/pcfread.c (pcf_get_encodings): Don't decrease j for
allocating `encoding'.
* src/base/ftobjs.c (FT_Load_Glyph, FT_Get_Glyph_Name): Fix
bounding tests.
* src/bdf/bdfdrivr.c (BDF_CMapRec) [FT_CONFIG_OPTION_USE_CMAPS]:
New structure.
(bdf_cmap_init, bdf_cmap_done, bdf_cmap_char_index,
bdf_cmap_char_next) [FT_CONFIG_OPTION_USE_CMAPS]: New functions.
(BDF_Get_Char_Index) [!FT_CONFIG_OPTION_USE_CMAPS]: Use only
conditionally.
(BDF_Face_Init): Handle `AVERAGE_WIDTH' and `POINT_SIZE' keywords.
Implement new cmap handling.
(bdf_driver_class): Updated.
* src/sfnt/ttload.c, src/bdf/bdflib.c: removing compiler warnings
* src/type42/t42objs.c: removed the bug that prevented un-hinted
outlines to be loaded
src/base/ftobjs.c, src/objs/fttype1.c, src/sfnt/ttcmap0.c,
src/smooth/ftgrays.c: changed uses of "setjmp" and "longjmp"
to "ft_setjmp" and "ft_lonjmp". Removed direct references to
<stdio.h> and <setjmp.h> when appropriate, to eventually replace
them with a FT_CONFIG_STANDARD_LIBRARY_H. Useful for the XFree86
Font Server backend based on FT2.
src/cache/ftccache.i, src/cache/ftcsbits.c: adding various
experimental optimisations to the cache manager
* src/type42/t42parse.c: removing duplicate function
src/type42/t42parse.h, src/type42/t42objs.h, src/type42/t42objs.c,
src/type42/type42.c:
updated the Type42 driver by splitting it into several files since
it makes the code easier to read and maintain. Also fixed the bug
that prevented the correct display of fonts with "ftview"
(_bdf_parse_glyphs): Use correct size for allocating
`font->unencoded'.
(bdf_load_font): Free array conditionally.
Return proper error code in case of failure.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Make it more robust against
unusual fonts.
amiga/include/freetype/config/ftmodule.h: Updated to include
support for BDF and Type42 drivers.
* docs/modules.txt: Updated.
* src/bdf/bdflib.c (_bdf_parse_glyphs): Replace floating point math
with calls to `FT_MulDiv'.
FT_Get_X11_Font_Format to return an X11-compatible string describing the
font format of a given face. This was put in a new optional base source
file, corresponding to a new public header (named FT_XFREE86_H since
this function should only be used within the XFree86 font server IMO).
* include/freetype/config/ftheader.h: adding FT_XFREE86_H, though it's
not documented yet.
* include/freetype/t1tables.h, src/base/fttype1.c: adding two new APIs
named "FT_Get_PS_Font_Info" and "FT_Has_PS_Glyph_Names". This required
a new optional source in 'src/base' named "fttype1.c"
* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: updating
build control files for the new files "ftxf86.c" and "fttype1.c" in
src/base
src/sfnt/sfobjs.c, src/sfnt/sfdriver.c, src/base/ftnames.c:
fixing the SFNT name table loader to support various buggy fonts.
it now ignores empty name entries, entries with invalid pointer
offsets and certain fonts containing tables with broken "storageOffset"
fields.
name strings are now loaded on demand, which reduces the memory
requirements for a given FT_Face tremendously (for example, the
name table of Arial.ttf is about 10Kb and contains 70 names !!)
finally, this is a _quick_ fix. The whole name table loader and
interface will be rewritten in a much more cleanly way shortly,
once CSEH have been introduced in the sources.
FT_MUNMAP_PARAM from aclocal.m4 into here, so aclocal.m4 can be
rebuilt from sources. Set macro serial to 1, and use third argument
to AC_DEFINE for our two custom symbols, so ftconfig.in could one day
be rebuilt with autoheader (not recommended now, ftconfig.in is a
custom source file)
(t1_toint): Use it to handle numbers in radix format.
* src/psaux/t1decode.c (T1_Decoder_Parse_Charstrings): Add dummy
for undocumented, obsolete opcode 15.
src/base/descrip.mms, src/base/Jamfile, src/base/rules.mk:
Adding a new API called "FT_Get_BDF_Charset_ID" to retrieve
BDF-specific strings from a face. This is much cleaner
than accessing the internal types "BDF_Public_Face" defined in
FT_INTERNAL_BDF_TYPES_H
* src/cff/cffdrivr.c, src/cid/cidriver.c, src/pcf/pcfdriver.c,
src/truetype/ttdriver.c, src/type1/t1driver.c,
src/winfonts/winfnt.c, src/type42/t42drivr.c, src/bdf/bdfdrivr.c
[FT_CONFIG_OPTION_DYNAMIC_DRIVERS]: Completely removed. It has
been never used.
(parse_font_matrix): Remove unnecessary code.

bug that prevented FreeType 2.x and FreeType 1.x to produce
bit-by-bit identical monochrome glyph bitmaps with native TrueType
hinting. The culprit was a single-bit flag that wasn't set
correctly by the TrueType glyph loader !!

adding OpenType Layout source files. Module is still incomplete
adding a generic implementation of dynamic hash tables using
linear algorithm (to get rid of 'stalls' during resizes). This
will be used in the future in at least three parts of the
library: the cache sub-system, the object sub-system and
the memory debugger.
* include/freetype/internal/ftcore.h: added this header file to
group all new definitions related to exception handling and
memory management. It's very likely that this file will disappear
or be renamed in the future..
* include/freetype/internal/ftobject.h, include/freetype/ftsysmem.h:
adding comments to better explain the object sub-system as well
as the new memory manager interface.
caused FreeType to crash when certain broken fonts (e.g.
"hya6gb.ttf") were opened.
* src/sfnt/ttload.c (TT_Load_Names): applied a small work-around to
manage fonts containing a broken name table (e.g. "hya6gb.ttf")
* src/sfnt/ttcmap0.c (tt_cmap4_validate):
fixed over-restrictive validation test. the charmap validator
now accepts overlapping ranges in format 4 charmaps.
* src/sfnt/ttcmap0.c (tt_cmap4_char_index):
switched to a binary search algorithm. Certain fonts contain
more than 170 distinct segments !!

OS X.
(is_dfont) [TARGET_API_MAC_CARBON]: Define only for OS X.
Handle `nameLen' <= 6 also.

Conditionalize some code for OS X.
Add code to call normal loader as a fallback.
Some more variable renames to avoid troubles on the Mac.

* include/freetype/config/ftmodule.h,
include/freetype/internal/fttrace.h,
src/Jamfile, src/pfr/*:
adding a PFR font driver to the FreeType sources. Not that it
doesn't support embedded bitmaps or kerning tables for now..
* include/freetype/internal/ftmemory.h: adding the FT_MEM_ZERO
and FT_ZERO macros
* include/freetype/internal/ftstream.h: adding the FT_NEXT_OFF3,
FT_NEXT_UOFF3, FT_NEXT_OFF3_LE and FT_NEXT_UOFF3_LE to parse
in-memory 24-bit integers.
builds/amiga/src/base/ftdebug.c :
2.1.0 couldn't be linked against applications in Win32 and
Amiga builds due to changes to "src/base/ftdebug.c" that
were not properly propagated to "builds/win32" and
"builds/amiga"..
this has been fixed. We'll probably make 2.1.1 real
soon now..

added the new configuration file "ftstdlib.h" used to define
aliases for all ISO C library functions used by the engine
(e.g. strlen, qsort, setjmp, etc...)
this eases the porting of FreeType 2 to exotic environments like
XFree86 modules/extensions..
also removed many #include <string.h>, #include <stdlib.h>, etc...
from the engine's sources where they're not needed..
FT_LOCAL and FT_LOCAL_DEF, respectively, as with other ftconfig.h
files.
* builds/unix/ftconfig.in: Add argument to FT_LOCAL and
FT_LOCAL_DEF.

src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
src/sfnt/ttload.c, src/sfnt/ttcmap0.c, src/sfnt/ttcmap0.h:
updated the SFNT charmap support to use FT_CMaps
changed the names of memory macros. Examples:
MEM_Set => FT_MEM_SET
MEM_Copy => FT_MEM_COPY
MEM_Move => FT_MEM_MOVE
ALLOC => FT_ALLOC
FREE => FT_FREE
REALLOC = >FT_REALLOC
FT_NEW was introduced to allocate a new object from a _typed_
pointer..
note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
arguments.
This results in _lots_ of sources being changed, but makes the
code more generic and less error-prone..
src/type1/t1cmap.c: updating and moving the Type 1 FT_CMap support
from "src/type1" to "src/psaux" since it's going to be shared
by the Type 1 and CID font drivers..
* src/psaux/Jamfile, src/psaux/psaux.c, src/psaux/psauxmod.c,
