Title: Minor render loop cleanup.

If targeting a specific fps; there's no need for us to call `getTimestamp` ourselves because the requestAnimationFrame callback passes us in the frame time (specifically a DOMHighResTimeStamp)

I also made a tweak to the requestAnimationFrame polyfill to use `getTimestamp` instead of `Date.now` so that we use higher resolution timers if they are available.
