  A title generator that uses the Pango international text layout and Freetype2 
  font renderer.
notes: >
  Supplying a filename with extension ".txt" causes the loader producer to load 
  with pango. If the filename begins with "+" the pango producer interprets the 
  filename as pango text. This is a shortcut to embed titles in melt commands. 
  For MLT XML, it is recommended that you embed the title text in the property 
  value.
  
  Pango has builtin scaling. It will rescale the originally rendered title to
  whatever the consumer requests. Therefore, it will lose its aspect ratio if 
  so requested, and it is up to the consumer to request a proper width and 
  height that maintains the image aspect.
