Testing to see if drawing a quad is faster than drawing two triangles. In principle it should be but it will depend on how efficient the actual drawing procedures are. Until we get the flash timing issues sorted out, I'm putting back in the screen updates...USE TURBO MODE!
Triangle code is @WO997's from his already blindingly fast 3d renderer at http://scratch.mit.edu/projects/50080282/ This test uses horizontally aligned quads. The same test could be done for vertically aligned quads, but since the algorithm is identical it will be the same speed...
