  PANGO_GLYPH_EMPTY is now defined to mean a "draw nothing" glyph.  This
  was what glyph 0 was used for previously.  As a result, bumped up the
  Pango module version, meaning that modules compiled against earlier
  versions are probably not compatible with this release. [#73147]
* New framework in examples for building a binary called pango-view,
  that can be used to render a text file using any of the available
  backends.  This is installed into bindir now.

  binary compatibility.
