/*
  vo_ggi.c - General Graphics Interface (GGI) Renderer for MPlayer

  (C) Alex Beregszaszi
  
  Uses libGGI - http://www.ggi-project.org/

  TODO:
   * implement direct rendering support - NEEDS TESTING
   * implement non-directbuffer support - NEEDS TESTING
   * check on many devices
   * implement gamma handling (VAA isn't obsoleted?)
 
  BUGS:
   * palettized playback has bad colors, probably swapped palette?
   * fbdev & DR produces two downscaled images
   * fbdev & FLIP (& DR) produces no image

  Thanks to Andreas Beck for his patches.

  Many thanks to Atmosfear, he hacked this driver to work with Planar
  formats, and he fixed the RGB handling.
