[Freetype] FreeType 2.1.4 released

[David Turner]

Hello,

  Enough is enough, and I've just released FreeType 2.1.4 (codename: "Never A Dull 
Moment" :-)
  The package is available from the usual sources, whose addresses are found 
below:

     http://sourceforge.net/project/showfiles.php?group_id=3157
     ftp://ftp.freetype.org/freetype/freetype2/

  We can now hapilly start hacking on 2.1.5, whose purpose will hopefully be to 
fix
  those nasty bugs that didn't make it in this release, as well as integrate a 
_small_
  number of new features (e.g. Graham's "unpatented" patch or Juliusz 
improvements to
  support for SFNT-based bitmap font files); in the hope that the result will 
be an
  acceptable candidate for a new stable release like 2.2

Cheers,

- David Turner

====================================================================================================
LATEST CHANGES BETWEEN 2.1.4 and 2.1.3

  I. IMPORTANT BUG FIXES

    - updated to newest libtool version, fixes build problems on various
      platforms.

    - a fix in the Gzip stream reader, it couldn't read certain .gz files
      properly due to a small typo. In certain cases, FreeType could also
      loop endlessly when trying to load tiny gzipped files.

    - the configure script now tries to use the system-wide zlib when
      it finds one (instead of the copy found in src/gzip). And
      "freetype-config" has been updated to return relevant flags in this
      case when invoked with "--libs" (e.g. "-lzlib")

    - certain fonts couldn't be loaded by 2.1.3 because they lacked a
      Unicode charmap (e.g. SYMBOL.TTF). FreeType erroneously rejected
      them.

    - the CFF loader was modified to accept fonts which only
      contain a subset of their reference charset. This prevented the
      correct use of PDF-embedded fonts.

    - the logic to detect Unicode charmaps has been modified. this is required
      to support fonts which include both 16-bit and 32-bit charmaps (like
      very recent asian ones) using the new 10 and 12 SFNT formats.

    - the TrueType loader now limits the depth of composite glyphs. This is
      necessary to prevent broken fonts to break the engine by blowing the
      stack with recursive glyph definitions.

    - the CMap cache is now capable of managing UCS-4 character codes that
      are mapped through extended charmaps in recent TrueType/OpenType fonts

    - the cache sub-system now properly manages out-of-memory conditions,
      instead of blindly reporting them to the caller. This means that it
      will try to empty the cache before restarting its allocations to see
      if that can help.

    - the PFR driver didn't return the list of available embedded bitmaps
      properly.

    - there was a nasty memory leak when using embedded bitmaps in certain
      font formats.

  II. IMPORTANT CHANGES

    - David Chester contributed some enhancements to the auto-hinter that
      significantly increase the quality of its output. The Postscript hinter
      was also improved in several ways..

    - the FT_RENDER_MODE_LIGHT render mode was implemented

    - a new API, called FT_Get_BDF_Property has been added to FT_BDF_H to
      retrieve BDF properties from BDF _and_ PCF font files. THIS IS STILL
      EXPERIMENTAL, since it hasn't been properly tested yet.

    - a Windows FNT specific API has been added, mostly to access font
      headers. This is used by Wine

    - TrueType tables without a "hmtx" table are now tolerated when an
      incremental interface is used. This happens for certain Type42 fonts
      passed from Ghostscript to FreeType.

    - the PFR font driver is now capable of returning the font family and
      style names when they're available (instead of the sole "FontID"). This
      is performed by parsing an *undocumented* portion of the font file !!

  III. MISCELLANEOUS

    - the path stroker in FT_STROKER_H has entered beta stage. It now works
      very well, but it's interface might change a bit in the future. More
      on this in later releases

    - the documentation for FT_Size_Metrics didn't appear properly in the
      API reference

    - the file docs/VERSION.DLL has been updated to explain versioning
      with FreeType (i.e. comparing release/libtool/so numbers, and how
      to use them in Autoconf scripts)

    - the installation documentation has been seriously revamped. Everything
      is now in the "docs" directory.
