Overview of changes between 1.2.x and 1.3.0
===========================================
* Share modules between the FT2 and Xft backend. Export PangoFcFont
  and PangoFcFontMap base classes so that other fontconfig based
  backends can be written and use these same modules.
* Redo module system to use GTypeModule and work much like GTK+ theme
  engines and input method modules.
* Change modules to declare coverage by script, rather than by code
  point. Add a ->covers callback so that modules can dynamically
  decide whether they can cover a particular codepoint with a given
  font. (This will allow multiple modules to handle a script for
  different types fonts.)
* Complete rewrite of itemization pass. Now uses script information to
  improve language tags. This solves problems with incorrect language
  tags resulting in drastically wrong fonts being selected by
  fontconfig.
* Add backspace-deletes-character PangoLogAttr; will allow proper
  deletion behavior for non-Western scripts.  [Noah Levitt]
* Add pango_fc_font_kern_glyphs(), which speeds up kerning a lot over
  doing it pair-by-pair. [Soeren Sandmann]. Kern in the Xft backend as
  well as the FT2 backend.
* Remove the X font backend, except a minimal set of stubs to maintain
  binary compatibility.
* Many improvements to pangoft2topgm to allow displaying PangoMarkup,
  saving to different file formats, etc.
* Convert build system to automake-1.7; many cleanups and
  improvements. [James Henstridge]
* Documentation additions and improvements [Matthias Clasen, Martin
  Pool]; add man pages for the included binaries.  [Matthias]
