Werner Lemberg e6e6eade04 Finish fix of scaling bug of CID-keyed CFF subfonts.
* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
functions.

* src/cff/cffobjs.h (CFF_Internal): New struct.  It is used to
provide global hinting data for both the top-font and all subfonts
(with proper scaling).

* src/cff/cffobjs.c (cff_make_private_dict): New function, using
code from `cff_size_init'.
(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
Use CFF_Internal and handle subfonts.
(cff_face_init): Handle top-dict and subfont matrices correctly;
apply some heuristic in case of unlikely matrix concatenation
results.  This has been discussed with people from Adobe (thanks
goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
and not correct.

* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.

* src/cff/cffgload.c (cff_builder_init): Updated.
(cff_decoder_prepare): Handle hints globals for subfonts.
Update all callers.
(cff_slot_load): Handling scaling of subfonts properly.

* src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.
(cff_parse_font_matrix): Use it.

* src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em'
FT_ULong.

* docs/CHANGES: Document it.

Werner Lemberg fb57228b94 * src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init):

Werner Lemberg 210d61894b Fix support for subsetted CID-keyed CFFs.
* include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED,
FT_IS_CID_KEYED): New macros.

* src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the
maximum CID value in CID-keyed CFFs.
Handle FT_FACE_FLAG_CID_KEYED flag.

* docs/CHANGES: Document it.


Fix CFF font matrix calculation and improve precision.

* src/cff/cffparse.c (cff_parse_real): Increase precision if integer
part is zero.
(cff_parse_font_matrix): Simplify computation of `units_per_em';
this prevents overflow also.


Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts.

* src/cid/cidriver.c: Include FT_SERVICE_CID_H.

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

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.
