Upgrade freetype to 2.4.6cm-7.1.0gingerbread-releasegingerbreadgb-release-7.2

CHANGES BETWEEN 2.4.5 and 2.4.6

  I. IMPORTANT BUG FIXES

    - For TrueType based fonts, the ascender and descender values were
      incorrect sometimes  (off by a pixel if the ppem value was not a
      multiple of 5).   Depending on the use you might now  experience
      a different  layout; the  change should  result in  better, more
      consistent line spacing.

    - Fix CVE-2011-0226  which causes a  vulnerability while  handling
      Type 1 fonts.

    - BDF fonts  containing  glyphs with negative values  for ENCODING
      were  incorrectly  rejected.  This  bug has  been introduced  in
      FreeType version 2.2.0.

    - David Bevan contributed a major revision of the FreeType stroker
      code:

      . The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.

      . A new  line join style,  FT_STROKER_LINEJOIN_MITER_FIXED,  has
        been introduced to support PostScript and PDF miter joins.

      . FT_STROKER_LINEJOIN_MITER_VARIABLE  has been introduced  as an
        alias for FT_STROKER_LINEJOIN_MITER.

      . Various stroking glitches has been fixed.

  II. MISCELLANEOUS

      - SFNT bitmap fonts which contain an outline glyph for `.notdef'
        only no longer set the FT_FACE_FLAG_SCALABLE flag.


CHANGES BETWEEN 2.4.4 and 2.4.5

  I. IMPORTANT BUG FIXES

    - A rendering regression  for second-order Bézier curves  has been
      fixed, introduced in 2.4.3.


  II. IMPORTANT CHANGES

    - If autohinting  is not  explicitly disabled,  FreeType now  uses
      the autohinter if  a TrueType based font doesn't  contain native
      hints.

    - The load flag FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH  has been made
      redundant and  is simply ignored;  this means that FreeType  now
      ignores the global advance width value in TrueType fonts.

  III. MISCELLANEOUS

    - `FT_Sfnt_Table_Info' can now return the number of SFNT tables of
      a font.

    - Support for PCF files compressed with bzip2 has been contributed
      by Joel  Klinghed.  To  make this  work, the  OS must  provide a
      bzip2 library.

    - Bradley  Grainger  contributed  project  and  solution  files in
      Visual Studio 2010 format.

    - Again some fixes to better handle broken fonts.

    - Some improvements to the B/W rasterizer.

    - Fixes to the cache module to improve robustness.

    - Just  Fill Bugs contributed (experimental) code to compute  blue
      zones for CJK Ideographs, improving the alignment of  horizontal
      stems at the top or bottom edges.

    - The `ftgrid' demo program  can now display  autohinter segments,
      to be toggled on and off with key `s'.


CHANGES BETWEEN 2.4.3 and 2.4.4

  I. IMPORTANT BUG FIXES

    - UVS support (TrueType/OpenType cmap format 14) support is fixed.
      This regression has been introduced in version 2.4.0.

  II. MISCELLANEOUS

    - Detect tricky fonts (e.g. MingLiU)  by the lengths and checksums
      of Type42-persistent subtables (`cvt ', `fpgm', and `prep') when
      a TrueType font without family name is given.  The previous fix,
      introduced in 2.4.3,  was too rigorous,  causing many  subsetted
      fonts (mainly  from PDF files) displayed badly  because FreeType
      forced  rendering with  the TrueType bytecode engine  instead of
      the autohinter.

    - Better support for 64bit platforms.

    - More fixes to improve handling of broken fonts.


CHANGES BETWEEN 2.4.2 and 2.4.3

  I. IMPORTANT BUG FIXES

    - Fix rendering of certain cubic, S-shaped arcs.   This regression
      has been introduced in version 2.4.0.

  II. MISCELLANEOUS

    - To  fix  the  above  mentioned  rendering  issue,  a  new spline
      flattening algorithm  has been  introduced which  speeds up both
      conic and cubic arcs.

    - Handling of broken fonts has been further improved.

+  *   Open a new stream to parse bzip2-compressed font files.  This is
+  *   mainly used to support the compressed `*.pcf.bz2' fonts that come
+  *   with XFree86.
+  *
+  * @input:
+  *   stream ::
+  *     The target embedding stream.
+  *
+  *   source ::
+  *     The source stream.
+  *
+  * @return:
+  *   FreeType error code.  0~means success.
+  *
+  * @note:
+  *   The source stream must be opened _before_ calling this function.
+  *
+  *   Calling the internal function `FT_Stream_Close' on the new stream will
+  *   *not* call `FT_Stream_Close' on the source stream.  None of the stream
+  *   objects will be released to the heap.
+  *
+  *   The stream implementation is very basic and resets the decompression
+  *   process each time seeking backwards is needed within the stream.
+  *
+  *   In certain builds of the library, bzip2 compression recognition is
+  *   automatically handled when calling @FT_New_Face or @FT_Open_Face.
+  *   This means that if no font driver is capable of handling the raw
+  *   compressed file, the library will try to open a bzip2 compressed stream
+  *   from it and re-open the face with it.
+  *
+  *   This function may return `FT_Err_Unimplemented_Feature' if your build
