Now Drawing 200,000+ blocks!

It's been a while because I have been trying out all kinds of optimization ideas. Using instancing per block type (and thus giving up depth based drawing, for now), every frame, 200,000+ blocks with randomly assigned block types, face rotations, and colors are drawn with constantly updating positions and 360 degree rotations, without lag! There is also global lighting with 4 general direction spot lights and 1 universal ambient light.

Also, I greatly improved the color variations (within each block) and was finally able to get multisampled anti-aliasing (MSAA) to work!
