--  <description>
--  A Gtk_Print_Settings object represents the settings of a print dialog in a
--  system-independent way. The main use for this object is that once you've
--  printed you can get a settings object that represents the settings the user
--  chose, and the next time you print you can pass that object in so that the
--  user doesn't have to re-set all his settings.
--
--  It's also possible to enumerate the settings so that you can easily save
--  the settings for the next time your app runs, or even store them in a
--  document. The predefined keys try to use shared values as much as possible
--  so that moving such a document between systems still works.
