As long as the timer's time interval is less than the screen refresh interval (and the technote says to simply assume 60Hz and that most drawing doesn't need more than 30Hz, so that's easy enough to assure) then it will work. And even if the timer is more, it will depend on the behavior of the event loop. If the event loop is smart it will process all queued events before running the next timer, in which case the technique will work even for a zero-interval timer, but I don't know if it actually works this way.
