/***************************************************************************
Vertex Array test. Tests wheater vertex arrays are faster or not.
As you can see by looking at the FPS, this is the reason why I am not using
vertex arrays. Mesa sucks dealing with vertex arrays. Windows may handle
them better but that's a diffrent story.
