OK. I'm just saying ... what makes you think it's not "down to the wire" in 
this case?  It doesn't look like you're doing anything in the inner loops of 
the tick that you couldn't do equally well in C, so why wouldn't the JIT 
generate equivalently efficient code?

Cool. I've only done large-scale manipulations, not drawing pixel-by-pixel, 
so I guess I never ran into that problem.
