/*
vo_ggi.c - General Graphics Interface (GGI) Renderer for MPlayer
(C) Alex Beregszaszi <alex@naxine.org>
Uses libGGI - http://www.ggi-project.org/
Thanks to Andreas Beck for his patches.
Many thanks to Atmosfear, he hacked this driver to working with Planar
formats, and he fixed the RGB handling.
