   2   vo_ggi.c - General Graphics Interface (GGI) Renderer for MPlayer
   3
   4   (C) Alex Beregszaszi
   5
   6   Uses libGGI - http://www.ggi-project.org/
   7
   8   TODO:
   9    * implement direct rendering support - NEEDS TESTING
  10    * implement non-directbuffer support - NEEDS TESTING
  11    * check on many devices
  12    * implement gamma handling (VAA isn't obsoleted?)
  13
  14   BUGS:
  15    * palettized playback has bad colors, probably swapped palette?
  16    * fbdev & DR produces two downscaled images
  17    * fbdev & FLIP (& DR) produces no image
  18
  19   Thanks to Andreas Beck for his patches.
  20
  21   Many thanks to Atmosfear, he hacked this driver to work with Planar
  22   formats, and he fixed the RGB handling.
