Overview of changes between 1.2.x and 1.3.0

* Share modules between the FT2 and Xft backend. Export PangoFcFont

  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.

  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.)

  improve language tags. This solves problems with incorrect language
  tags resulting in drastically wrong fonts being selected by
  fontconfig.

  deletion behavior for non-Western scripts.  [Noah Levitt]

  binary compatibility.

  saving to different file formats, etc.

  improvements. [James Henstridge]
