Added in some Draw Benchmarks:
I also very slightly changed the code to make it easier to use the three benchmarks. I think this added a fixed 0.02 second (1 frame) overhead into the benchmark from another goto. I decided this was near enough to not worry about too much.
Clearly the draw code improved at 1.27; though the curved line code is still hampered by the ROM code. It might not be fair to test that part, since it's so rarely used!
