patch v1

Patch to fix.  This does not account for timer inaccuracy, just paint latency. 
We could probably account for timer inaccuracy too by changing the local
variable to hold the system time at which we expected to get our next
startAnimation() callback, and then using the difference in expected and actual
times as the offset to the delay.  It's not clear to me whether that's a big
deal.  I'm happy to do it if it would be better.
