David Turner e3d6e94853 CHANGES BETWEEN 2.2.1 and 2.2.2
I. IMPORTANT BUG FIXES

    - Various integer overflows have been fixed.

    - PFB fonts with MacOS resource fork weren't  handled correctly on
      non-MacOS platforms.

    - The PCF font loarder has been seriously hardened against malformed
      font files.

  II. IMPORTANT CHANGES

    - the unpatented hinter is now part of the default build of the
      library, and we added code to automatically support "tricky"
      fonts that need it.

      what this means is that FreeType should "just work" with certain
      Asian fonts, like MingLiu, which cannot properly load without a
      bytecode interpreter, but fortunately do not use any of the
      patented bytecode opcodes.

      Note that the API didn't change, so you can still force
      unpatented hinting with a special parameter to FT_Open_Face
      as well.

      if you're an embedded systems developer, you might want to
      *disable* the feature to save code space by undefining
      TT_CONFIG_OPTION_UNPATENTED_HINTING in ftoption.h.

    - LCD-optimized rendering is now disabled in all default builds
      of the library, mainly due to patent reasons. For more information
      see:

      http://lists.gnu.org/archive/html/freetype/2006-09/msg00064.html

      a new configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING has
      been introduced in ftoption.h; manually define it in this file
      if you want to re-enable the feature.

      the change only affects the implementation, not the FreeType API.
      This means that clients don't need to be modified, because the
      library still generates LCD decimated bitmaps, but with the added
      constraint that R=G=B on each triplet.

   - Some computation bugs in the TrueType bytecode interpreter were found,
     which allow us to get rid of very subtle and rare differences we had
     with the Windows renderer.

  III. MISCELLANEOUS

    - TrueType glyph loading is now about 25% faster.

    - the anti-aliased rasterizer has been optimized and is now 15% to 25%
      percent faster than the previous one, depending on content

    - the Type 1 loader has been improved; as an example, it now skips
      over top-level dictionaries properly

David Turner dad2a2de01 * src/cache/ftccache.h, src/cache/ftcglyph.h, src/cache/ftcimage.h,
src/cache/ftcsbits.h, src/cache/ftcmanag.h, src/cache/ftccmap.h,
    src/cache/ftcmru.h: copying the cache's internal header files which
    were located in 'include/freetype/cache' to the 'src/cache' directory
    instead.

    Note that these files are not used by FreeType clients, all cache
    public APIs have been already moved to include/freetype/ftcache.h,
    and the FT_CACHE_INTERNAL_XXXX_H macros all resolve to it.

    the move is to allow us to modify the internals without intereference
    from rogue clients. Note that there are no known client that accesses
    the cache internals at the moment.

Werner Lemberg 59939244ad Implement new, simplified module selection. With GNU make it is now
sufficient to modify a single file, `modules.cfg', to control the
inclusion of modules and base extension files.

This change also fixes the creation of ftmodule.h; it now depends on
`modules.cfg' and thus is rebuilt only if necessary.

Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
default location.

* modules.cfg: New file.

* builds/freetype.mk: Don't include `modules.mk'.
Include all `rules.mk' files as specified in `modules.cfg'.
(FTOPTION_FLAG, FTOPTION_H): New variables.
(FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.
Add FTOPTION_FLAG.
($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST.
(CONFIG_H): Add FTMODULE_H and FTOPTION_H.
(INCLUDES): Add DEVEL_DIR.
(INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ,
OBJ_M, OBJ_S): Use `:=', not `='.
(remove_ftmodule_h): New phony target to delete `ftmodule.h'.
(distclean): Add remove_ftmodule_h.

* builds/modules.mk: (MODULE_LIST): Removed.
(make_module_list, clean_module_list): Replace targets
with...
(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
variables.  Reason for the change is that it is not possible to have
a phony prerequisite which is run only if the target file must be
rebuilt (phony prerequisites act like subroutines and are *always*
executed).  We only want to rebuild `ftmodule.h' if `module.cfg' is
changed.
Update all callers.
($FTMODULE_H)): Rule to create `ftmodule.h', depending on
`modules.cfg'.

* builds/toplevel.mk: Rewrite and simplify module handling.
(MODULES_CFG, FTMODULE_H): New variables.
Include MODULES_CFG.
(MODULES): New variable to include all `module.mk' and `rules.mk'
files.  We no longer use make's `wildcard' function for this.

* Makefile (USE_MODULES): Remove.  Update all users.
(OBJ_DIR): Define it here.

* src/*/module.mk: Change

    make_module_list: foo
    foo: ...

to

    FTMODULE_H_COMMANDS += FOO
    define FOO
    ...
    endef

in all files.  `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.

* src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.

* builds/unix/detect.mk (setup): Always execute `configure' script.
(have_mk): Rename to...
(have_Makefile): This.
Don't use `strip' function.

* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is
defined.
(have_mk): Don't use `strip' function.
Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
accordingly).

* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.

* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
BUILD_DIR but DEVEL_DIR for development header files.

* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),
builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in
(TOP_DIR, OBJ_DIR): Removed.  Defined elsewhere.

* builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR),
builds/win32/win32-def.mk (OBJ_DIR): Removed.  Defined elsewhere.

* builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for
development header files.
Don't define PLATFORM.

* configure: Copy `modules.cfg' to builddir if builddir != srcdir.
Update snippet taken from autoconf's m4sh.m4 to current CVS version.
Be more verbose.

* include/freetype/config/ftmodule.h: Add comments -- this file is
no longer used if FreeType is built with GNU make.

* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,
docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.
Other minor updates.

* modules.txt: Removed.  Contents included in `modules.cfg'.


* include/freetype/internal/ftmemory.h (FT_QAlloc_Debug,
FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos.

* src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug,
FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug)
[FT_STRICT_ALIASING]: Implement.

src/winfonts/winfnt.c (FNT_Size_Request, FNT_Size_Select): Do size
matching for request of type NOMINAL and REAL_DIM.

* src/winfonts/winfnt.c (FNT_Face_Init): Print trace message when
`pixel_height' is used for nominal height.

* src/base/ftobjs.c (FT_Request_Size): Call `FT_Match_Size' if the
face is bitmap only and driver doesn't provide `request_size'.  This
is added merely for completion as no driver satisfies the conditions.

The next release will be 2.2.0, so don't worry about source code
backwards compatibility.

* include/freetype/ftimage.h (FT_Outline_MoveToFunc,

  . loader->pp3.y and loader->pp4.y are in 26.6 format, not in font
    units.
  . As we use the glyph's cbox to calculate the top bearing now
    there iss no need to adjust `top'.
