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

builds/unix/install.mk yet..
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..
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 ??
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).

Function names are now all uniformly prefixed with `gray_'.
* src/smooth/ftgrays.c: Include <setjmp.h>.
(ErrRaster_MemoryOverflow): New macro.
(TArea): New type to store area values in each cell (using `int' was
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

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..

* 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.

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.

Added support for clipped direct rendering in the smooth renderer.
* src/cff/t2objs.c (T2_Init_Face): For pure CFF fonts, set
`disable_horz_edges', `disable_vert_edges'.

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'.

(FT_Glyph_Done -> FT_Done_Glyph).
* include/freetype/ttnameid.h: Added some new Microsoft language
codes and LCIDs as found in Office Xp.

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.
and empty lines in output.

and index pages. It also supports wildcards on non Unix systems.
* include/freetype/*.h, include/freetype/cache/*.h: Updated comments
to include section definitions/delimitations for the API Reference
generator.
* include/freetype/freetype.h: Moved declaration of
`FT_Generic_Finalizer' and the `FT_Generic' structure to...
* include/freetype/fttypes.h: here.
* builds/os2/detekt.mk, builds/win32/detekt.mk: Moved comment to
avoid trailing spaces in variable.
* builds/freetype.mk: Use $(D) instead of $D to make statement more
readable.
* docs/docmaker.py: Formatting.
* src/psaux/psauxmod.c: Fixed a broken inclusion of component
header files (an FT_FLAT_COMPILE test was missing).
* src/cache/ftcmanag.c (FTC_Manager_Done): Fixed a bug that caused
an occasional crash when the function was called (due to a dangling
pointer).
* src/base/ftsystem.c (FT_Done_Memory): Fixed an obvious bug:
The ANSI "free()" function was called instead of "memory->free()".
* docs/docmaker.py: Added section filtering, multi-page generation
(index page generation is still missing though).
* builds/unix/install.mk, builds/unix/ft2unix.h: The file "ft2unix.h"
is now installed as <ft2build.h> for Unix systems. Note that we
still use the "freetype2/freetype" installation path for now.
* many files: Now using <ft2build.h> as the default build and setup
configuration file in all public headers. Internal source files
still need some changes though.
* builds/devel/ft2build.h, builds/devel/ftoption.h: Created a new
Win32 developer builds.
builds/win32/w32-dev.mk: Changed the developer build targets to
"devel-gcc" and "devel-bcc" in order to be able to develop with the
Borland C++ compiler.
the basic parsing routines seem to work ok
we now generate a list of DocBlock objects from
a list of input file, we now need to sort them
by "kind" (i.e. type/macro/functions) to generate
several web pages, as well as a global index
- note that the "modules.html" will soon disappear, it is now replaced
by a more general and more detailed series of pages named "design-??.html"
- the images have been seriously reworked, more will come tomorrow
the design of FT2 has evolved considerably since
these documents were written, and it's better not to
include them in order to avoid confusion among
users of the library..
Tons of unnecessary stuff have been removed; only the essential rules
have been retained.
The source files now depend on all header files in include/freetype,
include/freetype/config, and include/freetype/internal. This is not
optimal, I know, and I'll try to improve this, but it is better than
before (namely no dependencies on `internal').
FTDEBUG_SRC has been added (similar to FTSYS_SRC) -- I don't know
exactly whether this is really useful, but it doesn't harm.
There is now more documentation in the makefiles itself.
io-frames.html: Use of <th>, <code>, and <var> for better tagging.
Reactivating of FT_DEBUG_LEVEL_xxx macros.
Added a lot of #include directives to make `multi' builds possible -- note
that currently the modules cid, t1, and t1z have clashing structures and
functions which means that you can only use one of these three modules for a
multi build.
Added some missing function declarations to (local) header files.
Renamed some T1_Open_Face() to CID_Open_Face() in the cid module -- a lot
of other functions should be renamed also...
Replaced many FT_xxx stuff with T1_xxx in t1z driver -- this isn't finished
yet...
Fixed FT_Free() to allow a NULL pointer without an assertion (this has
always been a valid assumption in FreeType, at least in FT 1.x).
A lot of other, minor fixes (mostly documentation).
There is still some work on it to allow the following:
- multiple input files
- block classification according to block's first markers
(e.g. types, functions, constants, etc..)
- indexing and cross-linking
- better layout ;-)
taken from the correct location)
plus a small update in the tutorial to reflect the fact that
we know use the "freetype" directory prefix for header
inclusion
for the upcoming new "psnames" pseudo-driver
("psnames" is a module in charge of converting a
glyph name into a unicode value, or a Mac index
into a glyph name. It contains a copy of the Adobe
Glyph List + some logic to understand the "uniXXX"
named characters).
basic i/o access are performed with FreeType 2.
Note that unlike FT 1.x, you don't need to recompile the library if
you want to provide your own memory manager or your own i/o streams.
also, changed all image references to the new PNGs
Note that this document is really out-of-date
(there are no more resources, the stream manager has disappeared,
the build systel was seriously modified, etc..)
Updated all image references to the new PNGs
Note that this document is slightly out-of-date though..
(FT_Raster_Map was changed for FT_Bitmap, and the anti-alias renderer
now supports 128 levels by default).
