/*
vo_ggi.c - General Graphics Interface (GGI) Renderer for MPlayer
(C) Alex Beregszaszi <alex@naxine.org>
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:
* 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.
