I have three questions

1.) How does that make it faster
2.) Will you ever stop optimizing! ;)

3.) Am I the only one who figured out how findpixel works line by line? It
took me many hours to do so, now I am afraid to death of your putSprite,
that will take decades to figure out. You guys need to add those
strategically placed comments once and a while  :-)
