*Complete* rewrite of the cache sub-system to "solve" the
following points:
- all public APIs have been moved to FT_CACHE_H, everything
under "include/freetype/cache" is only needed by client
applications that want to implement their own caches
- a new function named FTC_Manager_RemoveFaceID to deal
with the uninstallation of FaceIDs
- the image and sbit cache are now abstract classes, that
can be extended much more easily by client applications
- better performance in certain areas. Further optimizations
to come shortly anyway...
- the FTC_CMapCache_Lookup function has changed its signature,
charmaps can now only be retrieved by index
- FTC_Manager_Lookup_Face => FTC_Manager_LookupFace
FTC_Manager_Lookup_Size => FTC_Manager_LookupSize (still in
private header for the moment)

include/freetype/internal/internal.h (FT_SERVICE_POSTSCRIPT_NAMES):
added new service to handle glyph name dictionaries, replacing
the old internal header named "psnames.h" by "services/svpsname.h"
note that this is different from "services/svpostnm.h" which only
handles the retrieval of Postscript font name for a given face.
(should we merge these two services into a single header ??)

heavy internal modifications to introduce the concept of
"module services". This is the first step towards a massive
simplification of the engine's internals, in order to
get rid of various numbers of hacks.
Note that this changes will break source & binary compatibility
for authors of external font drivers.
Maybe 2.1.6 will be called 2.2.0 after all :-)

defined to return the baseline-to-baseline distance. This was
already the value returned by the BDF and PCF drivers.
The `width' field now gives the average width. I wasn't able to
find something better. It should be taken as informative only.
New fields `size', `x_ppem', and `y_ppem'.

Redesigning the FNT driver to return multiple faces, not multiple
strikes. At least one font (app850.fon from WinME) contains
different FNT charmaps for its subfonts. Consequently, the previous
design of having multiple bitmap strikes in a single font face fails
since we have only one charmap per face.
* include/freetype/internal/fnttypes.h (FNT_Size_Rec): Removed.

bitmap width is now ignored.
(FNT_Load_Glyph): Updated.
Fix glyph index computation.
(winfnt_driver_class): Updated.
* src/sfnt/ttload.c (tt_face_load_hdmx): Don't assign
num_records until we actually decide to load the table,
otherwise, we'll segfault in tt_face_free_hdmx.
computation of glyph_index.
(FNT_Size_Set_Pixels): To find a strike, first check pixel_height
only, then try to find a better hit by comparing pixel_width also.
Without this fix it isn't possible to access all strikes.
Also compute metrics.max_advance to be in sync with other bitmap
drivers.
* src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code.
(FT_Set_Pixel_Size): Assign value to `metrics' after validation of
arguments.
Synchronize computation of height and width for bitmap strikes. The
`width' field in the FT_Bitmap_Size structure is now only useful to
enumerate different strikes. The `max_advance' field of the
FT_Size_Metrics structure should be used to get the (maximum) width
of a strike.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.
* src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.

. In all makefiles `/' is used as the path separator. The
conversion to the real path separators is done as late as
possible using $(subst ...).
. $(HOSTSEP) no longer exists. Now, $(SEP) gives the path separator
for the operating system, and the new $(COMPILER_SEP) the path
separator for the compiler tools.
. $(BUILD) has been renamed to $(BUILD_DIR). In general, all
directory variables end with `_DIR'. The variants ending in `_'
(like `BASE_' have been removed).

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.
* src/gzip/ftgzip.c (ft_gzip_file_io): Avoid zero value of `delta'
to prevent infinite loop.
* docs/VERSION.DLL: Provide better autoconf snippet to check
FreeType version.
* src/base/ftobjs.c (open_face): Free `internal' not
`face->internal' in case of error to avoid possible segfault.
* src/pshinter/pshalgo3.c (ps3_hints_apply): Check whether we
actually have an outline.
y_scale so that the top of non-capital letters is aligned on a pixel
boundary whenever possible.
* src/autohint/ahhint.c (ah_hint_edges): Make sure that lowercase
m's maintain their symmetry.
* include/freetype/config/ftoption.h [FT_CONFIG_OPTION_MAC_FONTS]:
New macro.
* src/base/ftobjs.c: Use it to control mac font support on non-mac
platforms.
Implement partial support of Mac fonts on non-Mac platforms.
* src/base/ftobjs.c (memory_stream_close, new_memory_stream,
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.
(ah_outline_compute_edges): Scale `edge_distance_threshold' down
after rounding instead of scaling comparison value in loop.
* src/autohint/ahhint.c (ah_hinter_align_stong_points): Provide
alternative code which runs faster.
Handle `before->scale == 0'.
* src/autohint/ahtypes.h (AH_SegmentRec): Move some fields down.
(AH_EdgeRec): Move some fields in structure.
New field `scale'.
* src/sfnt/ttcmap0.c (tt_cmap4_char_next): Use binary search.
`freetype.in'.
* builds/unix/configure: Regenerated.
* builds/unix/install.mk (install, uninstall): Handle `freetype.pc'.
* builds/unix/freetype2.in: New file. Contains building information
for the `pkg-config' package.
argument.
(bdf_get_font_property): Use `const' for third argument.
Updated all callers.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Set pixel width and height
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.
* src/type1/t1load.c: the Type 1 loader now accepts more general names
according to the Postscript spec (the previous one was too restrictive)
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

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'.

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

(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

* 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.

also.
* src/type42/t42parse.c (t42_parse_sfnts): Fix compiler warning.

* 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.

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

been never used.
(parse_font_matrix): Remove unnecessary code.
(parse_sfnts): Initialize some variables.
(t42_driver_class) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Use
ft_module_driver_has_hinter conditionally.
Moved some type 42 specific structure definitions to...
* include/freetype/internal/t42types.h: New file.
* include/freetype/internal/internal.h (FT_INTERNAL_T42_TYPES_H):
New macro.

`num_grays' for specifying the number of used gray levels.
* src/cache/ftcsbits.c (ftc_sbit_node_load): Initialize it.
Adding a driver for BDF fonts written by Francesco Zappa Nardelli
<Francesco.Zappa.Nardelli@ens.fr>. Heavily modified by me to
better adapt it to FreeType, removing unneeded stuff. Additionally,
it now supports Mark Leisher's BDF extension for anti-aliased
bitmap glyphs with 2 and 4 bpp.
* src/bdf/*: New driver.
* include/freetype/internal/bdftypes.h: New file.
* include/freetype/internal/fttrace.h: Added BDF driver components.

(ft2_dir, abs_curr_dir, abs_ft2_dir): New variables (code
partially taken from Autoconf).
Build a dummy Makefile if not building in source tree.
* docs/INSTALL: Document it.
bug that prevented FreeType 2.x and FreeType 1.x to produce
bit-by-bit identical monochrome glyph bitmaps with native TrueType

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:

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

* 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

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..

from the engine's sources where they're not needed..
FT_LOCAL and FT_LOCAL_DEF, respectively, as with other ftconfig.h

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

(i.e. FT_AutoHinter_Interface => FT_AutoHinter_ServiceRec,
FT_AutoHinter_Interface* => FT_AutoHinter_Service, etc..)
src/sfnt/sfdriver.c (get_sfnt_postscript_name): Fixed the loader so
that it accepts broken fonts like "foxjump.ttf", which made FreeType
crash when trying to load them.
Also improved the name table parser to be able to load
Windows-encoded entries before Macintosh or Unicode ones, since it
seems some fonts don't have reliable values here anyway.
src/cff/cffobjs.c (CFF_Face_Init),
src/cid/cidobjs.c (CID_Face_Init):
removing the bug that returned global BBox values in
16.16 fixed format (instead of integer font units).

Apply a small patch for AIX to make shared libraries work (this
patch is already in the CVS version of libtool).

typedef PS_StructRec T1_Struct; /* backwards-compatibility */

"foxjump.ttf" without allocating tons of memory and causing crashes..
the debug sub-system initialization. trace levels can now be specified
within the "FT2_DEBUG" environment variable. See the comments within

FT_ASSERT
* include/freetype/internal/ftextend.h, src/base/ftextend.c,

the "--prefix=/usr" was incorrectly sent to the "make" program..
the face object (face->toc.tables, face->root.family_name,

it appears they contain really funky glyphs..
there still is a bug there though.. !!

"MSung-Light-Acro" couldn't be rendered otherwise (it seems its
charstring is buggy, though this requires more analysis)..

aren't capable of directly computing a floating pointer constant casted
to FT_Fixed, and will link a math library instead !!
* src/cff/cffload.h, src/cff/cffload.c, src/cff/cffgload.c: updated

on hinted glyphs..
* src/cid/cidgload.c, src/cid/cidobjs.c, src/cid/cidobjs.h,
src/cid/cidriver.c, include/freetype/internal/t1types.h: added
Postscript hinter support to the CID font driver !!
(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
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 !!

builds/unix/install.mk yet..
GET_LongLE and GET_ULongLE which where incorrect (creating problems
in the pcf driver)..
* INSTALL: updated the instructions to build shared libraries with
Jam.. they were simply erroneous..
purposes..
* src/smooth/ftsmooth.c (ft_smooth_render): fixed a nasty hidden bug where
outline shifting wasn't correctly undone after bitmap rasterization. this
created problems with certain glyphs (like '"' of certain fonts..) and
the cache system..
* src/pshinter/pshalgo2.c (psh2_hint_table_init),
src/pshinter/pshalgo1.c (psh1_hint_table_init): removed compiler
warnings
* include/freetype/cache/*, src/cache/*: yet another massive rewrite of
the caching sub-system, in order to both increase performance and allow
simpler cache sub-classing. As an example, the code for the image and
sbit caches is now much simpler
I still need to update the documentation in www/freetype2/docs/cache.html

* src/autohint/ahglyph.c, src/autohint/ahhint.c: various fixes to
the auto-hinter. They merely improve the output of sans-serif fonts.
Note that there are still problems with serifed fonts and composites
(accented characters)
* tests/gview.c: updated the debugging glyph viewer to show the
hints generated by the "autohint" module
improvements to the memory debugger to report more information in
case of errors. Also, some allocations that occured through
REALLOC couldn't be previously catched correctly..
the debugging memory manager to report the location (source file name
+ line number) where leaked memory blocks are allocated in the source
file.. funny, isn't it ??
* src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if
we are working with a CID keyed CFF font. Otherwise, a variable
that was never allocated memory might freed. This is a correction
to the previous patch for freeing subfonts.
correct glyph names tables. This resulted in the unavailability of
certain glyphs like `Cacute', `cacute' and `lslash' in Unicode
charmaps, even if these were present in the font (causing problems
for Polish users).

get the needed data type.
(TCell, TRaster): Use it.
(TRaster): New element `jump_buffer'.
(gray_compute_cbox): Use `RAS_ARG' as the only parameter and get
`outline' from it.

Provide a public API to manage multiple size objects for a given
FT_Face in the new header file `ftsizes.h'.
* include/freetype/ftsizes.h: New header file,
* include/freetype/internal/ftobjs.h: Use it.
Remove declarations of FT_New_Size and FT_Done_Size (moved to
ftsizes.h).
* include/freetype/config/ftheader.h (FT_SIZES_H): New macro.
* src/base/ftobjs.c (FT_Activate_Size): New function.
* src/cache/ftcmanag.c: Include ftsizes.h.
(ftc_manager_init_size, ftc_manager_flush_size): Use
FT_Activate_Size.
fixed a bug in 'glnames.py' that prevented it from generating correct
glyph names table. This resulted in the unavailability of certain glyphs
like "Cacute", "cacute" and "lslash" in Unicode charmaps, even if these
were present in the font (causing problems for Polish users).
when memory pool overflow occurs), function names are now all prefixed
with "gray_", and a new type (TArea) is defined to store area value in
each cell (using "int" was too small on 16-bit systems)..
- reallocation bug in T1_Table_Add
- increased accuracy of units per EM computation in T1 fonts
- support "+" as valid font name character (used in embedded fonts)
* include/freetype/internal/tttypes.h (TT_CMap0, TT_CMap2, TT_CMap4,
TT_CMap6): Adding field `language'.
(TT_CMapTable): Removing field `language'.
Type of `length' field changed to FT_ULong.
Adding fields for cmaps format 8, 10, and 12.
(TT_CMapGroup): New auxiliary structure.
(TT_CMap8_12, TT_CMap10): New structures.

field to the new structures.
Fixed freeing of arrays in case of unsuccessful loads.
Added support for loading format 8, 10, and 12 cmaps.
(TT_CharMap_Free): Added support for freeing format 8, 10, and 12
cmaps.
(code_to_index4): Small improvement.
(code_to_index6): Ditto.
(code_to_index8_12, code_to_index10): New functions.
* src/sfnt/ttload.c (TT_Load_Metrics_Header): Updated to new
structure.
(TT_Load_CMap): Ditto.
* src/sfnt/sfobjs.c (tt_encodings): Add MS UCS4 table (before MS
Unicode).
