Changes 2.1.9:

  I. IMPORTANT BUG FIXES

    - The function  `FT_Get_CharMap_Index' was only declared,  without
      any  real  code.   For  consistency,  it  has  been  renamed  to
      `FT_Get_Charmap_Index'.   (This function is needed  to implement
      cmap caches.)

    - `FT_Outline_Get_BBox'  sometimes returned  incorrect values  for
      conic outlines (e.g., for TrueType fonts).

    - Handling of `bhed' table has been fixed.

    - The TrueType driver with enabled byte code interpreter sometimes
      returned artifacts due to incorrect rounding.  This bug has been
      introduced after version 2.1.4.

    - The BDF driver dropped the last glyph in the font.

    - The BDF driver now uses the DEFAULT_CHAR property (if available)
      to select a glyph shape for the undefined glyph.

  II. IMPORTANT CHANGES

    - George  Williams   contributed  code  to   handle  Apple's  font
      distortion technology found in GX fonts (`avar', `cvar', `fvar',
      and `gvar' tables;  the Multiple Masters  API has been  slightly
      extended to cope with the new functionality).

    - The `FT_GlyphSlotRec' structure has been extended:  The elements
      `lsb_delta' and  `rsb_delta' give the difference  between hinted
      and  unhinted  left and right  side bearings  if autohinting  is
      active.  Using those values can improve the inter-letter spacing
      considerably.   See the documentation of  `FT_GlyphSlotRec'  and
      the `ftstring' demo program how to use it.

  III. MISCELLANEOUS

    - A new  documentation file  `formats.txt' describes various  font
      formats supported (and not supported) by FreeType.
