While not a direct answer, I can tell you that you can get better
performance by drawing all of your tiles to a texture, then just moving the
single texture around. When you get to the edge of the texture, just draw
a new one with new tiles and offset the texture accordingly. If your tiles
cover the screen totally, you wont need to clear the screen either.
