  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
