So instead, we assume that the - framework's animation timer might fire whenever, but we only invoke the - screen hack's "draw frame" method when enough time has expired. - - This means two extra calls to gettimeofday() per frame.

So, if we use a 30 FPS - animationTimeInterval (33333 µs) and a screenhack takes 40000 µs for a - frame, there will be a 26666 µs delay until the next frame, 66666 µs - after the beginning of the current frame.
