Details

Using an odd window size with http://people.mozilla.org/~jmuizelaar/fishie/fishie-fast.html can make the difference between 3fps and 30fps. To reproduce this I need to turn the method jit (bug 637878). I assume that this has to do with having a division of the width or height producing a double instead of an int.

Jeff, do you see them running at wildly different speeds?

This is working fine now, and as fast as the competition.
