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

Adding a driver for BDF fonts written by Francesco Zappa Nardelli
<Francesco.Zappa.Nardelli@ens.fr>. Heavily modified by me to

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.

Use functionality of old p2c_str directly.

and FT_ZERO macros
* include/freetype/internal/ftstream.h: adding the FT_NEXT_OFF3,

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

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,

(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).
1.4.2.
Apply a small patch for AIX to make shared libraries work (this
patch is already in the CVS version of libtool).
* builds/unix/config.sub, builds/unix/config.guess: Updated to
recent versions.
* builds/unix/configure.ac: Fix typo
(AC_CONFIG_FILE->AC_CONFIG_FILES).
* builds/unix/configure: Regenerated.

FT_Get_Next_Char
* src/base/ftobjs.c: implemented FT_Get_First_Char and FT_Get_Next_Char
been touched, while keeping everything backwards-compatible..
* include/freetype/t1tables.h: re-naming structure types. This done
basically:
typedef T1_Struct_
{
} T1_Struct;
becomes:
typedef PS_StructRec_
{
} PS_StructRec, *PS_Struct;
typedef PS_StructRec T1_Struct; /* backwards-compatibility */
hence, we increase the coherency of the source code by effectuively
using the 'Rec' prefix for structure types..
names table loader. Invalid individual name entries are now handled
correctly. This allows the loading of very buggy fonts like
"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
"ftdebug.c" for more details
* include/freetype/internal/fttrace.h: new file to define the trace
levels used for debugging. it is used both to define enums and
toggle names for FT2_DEBUG
* src/base/ftobjs.c, src/base/ftstream.c: FT_Assert renamed to
FT_ASSERT
* include/freetype/internal/ftextend.h, src/base/ftextend.c,
src/base/Jamfile, src/base/rules.mk: removing "ftextend" from the
library, since it is now completely obsolete..

It didn't work correctly when several arguments were passed
to it. For example, when typing:
./configure --disable-shared --prefix=/usr
the "--prefix=/usr" was incorrectly sent to the "make" program..
the face object (face->toc.tables, face->root.family_name,
face->root.available_size, face->charset_encoding,
face->charset_registry are now freed). Thanks to Niels Moseley.
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")
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.. !!
