needed.
Run `autoupdate' on it.

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

Dos/Windows/OS/2 systems

* 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.

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,

Modified all "rules.mk" and "descrip.mms" accordingly..

until parse_font_bbox is changed before we use logical shift rights
in the assignments of `root->ascender', `root->descender', and
`root->max_advance_width'.

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.

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.

seac emulation provided by the Type 2 endchar operator.
(T2_Parse_CharStrings): Added seac emulation for the endchar
operator.
CFF_Done_Encoding, CFF_Done_Charset): Extended to load and parse the
charset/encoding tables, and free the memory used by them when the
CFF driver is finished with them. Added tables
be more general. The problem affected more than synthetic fonts.
Added an entry for changes to ahhint.c. I mistakenly committed
ahhint.c without removing unnecessay comments. Furthermore, I did not
remove some code that I had commented out. Silly me!
* *.mk: Implemented `platform' target to disable auto-detection.

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..

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.

configuration files used to determine the location of all public,
configuration, and internal header files for FreeType 2. Modified
all headers under "include/freetype" to reflect this change. Note
that we still need to change the library source files themselves
though.
builds/win32/detect.mk: Added new files to support compilation with
the free Borland C++ command-line compiler. Modified the detection
rules to recognize the new "bcc32" target in "make setup bcc32".
src/truetype/ttobjs.c, src/truetype/ttgload.c,
src/truetype/ttinterp.c: Fixed a few comparisons that Borland C++
didn't really like. Basically, this compiler complains when FT_UInt
is compared to FT_UShort (apparently, it promotes `UShort' to `Int'
in these cases).
in the "builds" directory
- modified a few files because BCC32 didn't like certain comparisons
(UInt compared with a UShort, apparently the UShort is promoted to
an Int)

BSD Make, and clarify the use of "make setup" (instead of "make")
for build configuration
