I added some more debug readouts in the top left that I can easily enable and disable. Also changed the clear color to white for the time being so we can see which faces are actually being drawn. I've also gone and sped up the rendering a little bit more. We used to drop to about 24FPS is large open areas. Now we can always stay above 30 since our early out in the loop is when the block we are checking is solid. We get a consistent 60 inside cave-like areas which is good.
