Summary: RESIDUAL: Decreasining SMUSH CPU load

Initial Comment:
Currently, Residual's SMUSH player will redraw frames
ever after they have been drawn once. The only thing
that keeps it from eating all available CPU time is
that there's a small delay in the main loop. On my
computer this can sometimes cause problems with
stuttering audio. I think I've seen the movie lag
behind a couple of times as well.

This patch should ensure that each frame is drawn only
once. I've tried it with the software renderer, where
it appears to work well.

I haven't really tried it with the OpenGL renderer,
since it's currently not working for me. My computer
starts swapping around the time Manny appears in the
intro movie, and runs out of memory well before the
movie ends. I don't think that has anything to do with
my patch, though.
