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
to reflect the new design though..
routine that created nasty alignment artefacts.
* src/pshinter/pshrec.c, tests/gview.c: debugging updates..
* src/smooth/ftgrays.c: de-activated experimental gamme support,
apparently, "optimal" gamma tables depend on the monitor type,
resolution and general karma, so it's better to compute them outside
of the rasterizer itself..
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
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..
(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 !!
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 ??
loading synthetic fonts to make sure that the font name and
subrotuines are not loaded twice. This is to remove a memory leak
that occurs because the original allocation for these objects is not
deallocated when the objects are read the second time.
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).

pool overflow occurs).
Function names are now all uniformly prefixed with `gray_'.
* src/smooth/ftgrays.c: Include <setjmp.h>.
(ErrRaster_MemoryOverflow): New macro.

too small on 16-bit systems). <limits.h> is included to properly
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

(gray_convert_glyph): Use it.
Provide a public API to manage multiple size objects for a given

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

macros.
(FT_NOERRORDEF): Removed.

details.

* 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..

Dos/Windows/OS/2 systems
* src/tools: added new directory to hold tools and test programs

Fix compiler warnings.
* src/base/ftcalc.c: Fix (potential) compiler warnings.
* src/base/ftcalc.c (FT_SqrtFixed): Corrected/optimized the 32-bit

64-bits integers, as it is _much_ faster than calling FT_Sqrt64 :-)
* src/base/ftbbox.c: Removed invalid "#include FT_BEZIER_H" line.
* src/base/ftbbox.c (BBox_Cubic_Check): Rewrote function to use
direct computations with 16.16 values instead of sub-divisions. It

Fixed the bezier stack depths.
* src/base/ftcalc.c (FT_MulFix): Minor rounding fix.

types on platforms where Autoconf is not available). Also removed

"objs".
* 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 add its own directory to the include path at
compile time. Modified all "rules.mk" and "descrip.mms"
accordingly.
* src/cid/cidobjs.c, src/cid/cidload.c, src/pcf/pcfread.c,
src/type1/t1load.c, src/type1/t1objs.c: Added a few casts to remove
compiler warnings in pedantic modes.

glyph name for glyph index via FT_Get_Glyph_Name().
In function cff_get_interface(), added support for getting a glyph
name via the "glyph_name" module interface (used in the function
FT_Get_Glyph_Name()). We use the new function get_cff_glyph_name().
FT_FACE_FLAG_GLYPH_NAMES only if FT_CONFIG_OPTION_NO_GLYPH_NAMES is
not defined. This is to add support for getting a glyph name from a
glyph index vi FT_Get_Glyph_Name().
* src/cff/cffgload.c (CFF_Load_Glyph): Set glyph control data to the
the Type 2 glyph charstring (used by conversion programs).
Submitted by Ha Shao <hashao@chinese.com>.

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
