/*
vo_ggi.c - General Graphics Interface (GGI) Renderer for MPlayer
(C) Alex Beregszaszi
Uses libGGI - http://www.ggi-project.org/
TODO:
* implement gamma handling (VAA isn't obsoleted?)
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.
