[Bf-committers] Improvement of BGE rendering for CAVE systems

[PabloVazquez.org]

BTW, I just tried it live yesterday :)

Here at Universidad Rey Juan Carlos in Móstoles (Madrid), it was awesome,
specially with 3D glasses, still some little things to fix, but the overall
experience is very rich, just needs cool graphics to make it more awesome!
