Improve vanilla ptc note rendering performance #15

Collage doesn't do any batching or caching for note rendering at all. Maybe it would be possible to add that.

Batching isn't really possible in 0.9.2.5 because it uses DirectDraw. However, completely replacing the note rendering loop with a custom one, rendering to a separate surface, and blitting it back to the primary surface is 2-3x faster than directly rendering the notes onto the primary surface (how vanilla does it). It should be possible to do batching in newer versions because they use d3d9, each fill_rect does its own DrawPrimitive call in vanilla.
