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.

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..
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note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer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/base/ftapi.c, src/base/ftobjs.c: updating the type definitions for
the auto-hinter module.
(i.e. FT_AutoHinter_Interface => FT_AutoHinter_ServiceRec,
FT_AutoHinter_Interface* => FT_AutoHinter_Service, etc..)
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")
* 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
to reflect the new design though..
produces smoother glyphs at small sizes for very little cost
* 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
(some platforms don't provide this ANSI function !!)
some changes to "ftsystem.c" implementations in order to use
the new memory debugger on Unix, VMS and Amiga too !!
by introducing another layer.
* include/freetype/fterrors.h (FT_ERRORDEF_, FT_NOERRORDEF_): New
macros.
(FT_NOERRORDEF): Removed.
* include/*/*err*.h: Use FT_ERRORDEF_ and FT_NOERRORDEF_.
details.
* include/freetype/internal/cfferrs.h,
include/freetype/internal/tterrors.h,
include/freetype/internal/t1errors.h: Removed. Replaced with files
local to the module. All extra error codes have been moved to
`fterrors.h'.
* src/sfnt/ttpost.h: Move error codes to `fterrors.h'.

src/smooth/ftsmerrs.h, src/truetype/tterrors.h,
src/type1/t1errors.h, src/winfonts/fnterrs.h: New files defining the
error names for the module it belongs to.
* include/freetype/ftmoderr.h: New file, defining the module error
offsets. Its structure is similar to `fterrors.h'.
* include/freetype/fterrors.h (FT_NOERRORDEF): New macro.
(FT_ERRORDEF): Redefined to use module error offsets.
All internal error codes are now public; unused error codes have
been removed, some are new.
* include/freetype/config/ftheader.h (FT_MODULE_ERRORS_H): New
macro.
* include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_USE_MODULE_ERRORS): New macro.
All other source files have been updated to use the new error codes;
some already existing (internal) error codes local to a module have
been renamed to give them the same name as in the base module.
All make files have been updated to include the local error files.
* src/cid/cidtokens.h: Replaced with...
* src/cid/cidtoken.h: This file for 8+3 consistency.
* src/raster/ftraster.c: Use macros for header file names.
created incorrect scale factors !!
* src/autohint/ahglobal.c, src/autohint/ahglyph.c, src/autohint/ahhint.c:
fixed the incorrect blue zone computations, and improved the composite
support. Note that these changes result in improved rendering, while
sometimes introducing their own artefacts. That's probably the last
big change to the autohinter before the introduction of its complete
replacement..
src/base/Jamfile, src/base/rules.mk: adding trigonometric functions
to the core API (using Cordic algorithms).
* builds/top_level.mk, builds/newline, builds/detect.mk: fixed problems
with Make on Windows 2000, as well as problems when "make distclean" is
invoked on a non-Unix platform when there is no "config.mk" in the
current directory..
* builds/freetype.mk: fixed a problem with object deletions under
Dos/Windows/OS/2 systems
* src/tools: added new directory to hold tools and test programs
moved docmaker.py, glnames.py to it..
* src/tools/docmaker.py: improved the script to add the current date
at the footer of each web page (useful to distinguish between versions)
* Jamfile: fixed incorrect HDRMACRO argument.
* TODO: removed the cubic arc bbox computation note, since it has been
fixed recently..
* include/freetype/t1tables.h, include/freetype/config/ftoption.h:
formatting
the structure of similar makefiles.
* builds/dos/*.mk: Ditto.
* builds/ansi/*.mk: Ditto.
* builds/win32/win32-def.mk (BUILD): Fix typo.
* builds/compiler/*.mk (CLEAN_LIBRARY): Don't use NO_OUTPUT.
This is already used in the link_*.mk files.
* src/*/Jamfile: Slight changes to make files more cryptic.
* include/freetype/config/ftheader.h: removed obsolete macros like
FT_SOURCE_FILE, etc.. and added cache-specific macro definitions that
were previously defined in <freetype/ftcache.h>. Added comments to be
included in a new API Reference section.
* src/*/*: removed the use of FT_SOURCE_FILE, etc.. now, each component
needs to added its own directory to the include path at compile time.
Modified all "rules.mk" and "descrip.mms" accordingly..
`disable_horz_edges', `disable_vert_edges'.
* src/autohint/ahhint.c (ah_hint_edges_3, ah_hinter_hint_edges): Use
them (and remove static variables with the same names).
* src/pcf/pcfutil.c (BitOrderInvert): Add `const'.
* docs/glnames.py: Updated to latest pstables.h changes.
* src/psnames/pstables.h: Add more `const'.
* src/pcf/pcfutil.c: Ditto.
* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Fixing typo
(FT_Glyph_Done -> FT_Done_Glyph).
* include/freetype/ttnameid.h: Added some new Microsoft language
codes and LCIDs as found in Office Xp.
* builds/hurd/detect.mk: New file. Added support to detect the GNU
Hurd operating system as Unix-like. Fix submitted by Anthony Fok
<foka@debian.org>.
* src/type1/t1gload.c (T1_Load_Glyph): Set glyph control data to the
the Type 1 glyph charstring (used by conversion programs).
Submitted by Ha Shao <hashao@chinese.com>.
* src/base/ftgrays.c (grays_sweep): The function didn't exit
immediately if `num_cells' was 0 as it should. Thanks to Boris for
finding this out.
* src/base/ftglyph.c (FT_Glyph_To_Bitmap): Fixed memory leak when
bitmap rendering fails (thanks to Graham Asher).
* docs/docmaker.py, include/freetype/*.h: Updated the DocMaker
script to support chapters and section block ordering. Updated the
public header files accordingly.
* src/base/ftglyph.c (FT_Glyph_Copy): Advance width and glyph format
were not correctly copied.
to use direct definitions. This is the only way to do these things
in a portable way :-( The rest of the code should follow shortly
though everything compiles now.
* builds/compiler/intelc.mk, builds/compiler/watcom.mk: New files.
* builds/win32/detect.mk: Added support for the Intel C/C++
compiler, as well as _preliminary_ (read: doesn't work!) support for
Watcom. Also added a new setup target. Type "make setup list" for
a list of supported command-line compilers on Win32.
* src/base/ftdebug.c: Added dummy symbol to avoid empty file if
conditionals are off.
include/freetype/internal/internal.h: fixed header inclusion macros
to use direct definitions. This is the only way to do these things
in a portable way :-( The rest of the code should follow shortly
though everything compiles now..
* builds/compiler/intelc.mk, builds/compiler/watcom.mk,
builds/win32/detect.mk: added support for the Intel C/C++ compiler,
as well as _preliminary_ (read: doesn't work !!) support for Watcom.
Also added a new setup target. Type "make setup list" for a list
of supported command-line compilers on Win32..
Removed. ANSI C doesn't (explicitly) allow macro expansion in
arguments using `##'.
(FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory
names directly. Make them configurable. Use `##' to strip leading
and trailing spaces from arguments.
* builds/unix/ft2unix.h: Adapted.
* src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream,
ft_close_stream): Use FT_CALLBACK_DEF.
* builds/unix/ftsystem.c: Use new header scheme.
(FT_Done_Memory): Use free() from FT_Memory structure.
* src/base/ftinit.c, src/base/ftmac.c: Header scheme fixes.
* include/freetype/config/ft2build.h (FT2_CONFIG_ROOT,
FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE,
FT_SOURCE_FILE): Use `##' operator to be really ANSI C compliant.
