  24  * @short_description: GObject wrappers for cairo structs.
  25  *
  26  * If GObject support has not been compiled in cairo, either by
  27  * explicitely disabling it or because the installed cairo version
  28  * does not provide them, a compatible selection of wrappers used
  29  * by ADG is provided anyway.
