Mesa/glu version.) But, by calculating the Model View matrix our selves we can save this matrix without having to read it back in from the video card. This hopefully allows us to save a few cpu cycles when rendering out the fragments because we can just use glLoadMatrixd() with the precalculated matrix for each tile rather than doing a push(), translate(), pop() for every fragment. Panel status defaults to off for now until it gets a bit more developed. Extract OpenGL driver info on initialization.
