14183ea0f8 First of all, a big thanks to Werner and Antoine for their latest work !!
* 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..

* src/raster/ftraster.c: Fix definition condition of MEM_Set().
* src/smooth/ftgrays.c (M_Y): Change value to 192.
* src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter.
Remove unused variable.

avoid compiler warnings.

Use `const'.
* src/pshinter/pshrec.c (ps_hints_close): Remove redundant
declaration.
* src/pshinter/pshalgo1.c (psh1_hint_table_init): Rename variables
to avoid shadowing.

adf07a930c * src/smooth/ftgrays.c: adding experimental "gamma" support. This
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

1f7f0e87e5 Complete redesign of error codes. Please check ftmoderr.h for more
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/autohint/aherrors.h, src/cache/ftcerror.h, src/cff/cfferrs.h,
src/cid/ciderrs.h, src/pcf/pcferror.h, src/psaux/psauxerr.h,
src/psnames/psnamerr.h, src/raster/rasterrs.h, src/sfnt/sferrors.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.

66cb4790bf * src/base/ftcalc.c (FT_DivFix): fixed a bug in the 64-bit code that
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..

    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:

Submitted by Ha Shao <hashao@chinese.com>.

bitmap rendering fails (thanks to Graham Asher).

* 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.

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.

ft_close_stream): Use FT_CALLBACK_DEF.

David Turner
54e7574946 defining new types to hold "internal" fields of public
objects:

  FT_Face_Internal, FT_Size_Internal, FT_Slot_Internal

these contain some fields that may change between releases
of FreeType, without affecting the size of FT_FaceRec,
FT_SizeRec, FT_GlyphSlotRec, etc.., which means that
drivers wouldn't need to be recompiled if we only add new
fields to an internal structure..

I plan to hack a few things related to the auto-hinter and
I need this move to ensure that we will not break binary
compatibility between 2.0 and 2.1 :-)
