Description

+++ This bug was initially created as a clone of Bug #1553912 +++

CHANGES BETWEEN 2.10.0 and 2.10.1

I. IMPORTANT BUG FIXES

• The bytecode hinting of OpenType variation fonts was flawed, since
  the data in the `CVAR' table wasn't correctly applied.

II. MISCELLANEOUS

• Auto-hinter support for Mongolian.

• For distribution, .tar.bz2' packages are replaced with.tar.xz'
  bundles.

• The handling of the default character in PCF fonts as introduced
  in version 2.10.0 was partially broken, causing premature abortion
  of charmap iteration for many fonts.

• If `FT_Set_Named_Instance' was called with the same arguments
  twice in a row, the function returned an incorrect error code the
  second time.

• Direct rendering using FT_RASTER_FLAG_DIRECT crashed (bug
  introduced in version 2.10.0).

• Increased precision while computing OpenType font variation
  instances.

• The flattening algorithm of cubic Bezier curves was slightly
  changed to make it faster. This can cause very subtle rendering
  changes, which aren't noticeable by the eye, however.

• The auto-hinter now disables hinting if there are blue zones
  defined for a `style' (i.e., a certain combination of a script and
  its related typographic features) but the font doesn't contain any
  characters needed to set up at least one blue zone.

• The `ftmulti' demo program now supports multiple hidden axes with
  the same name tag.

• ftview',ftstring', and ftgrid' got a-k' command line option
  to emulate a sequence of keystrokes at start-up.

• ftview',ftstring', and `ftgrid' now support screen dumping to a
  PNG file.

• The bytecode debugger, ttdebug', now supports variation TrueType fonts; a variation font instance can be selected with the new-d'
  command line option.
