Re: requestAnimationFrame time and DOMHighResTimestamp

Not many developers are using this first parameter, but a few are. I've
talked to a few who picked up on the high res timer and they agree that
it's a better and more useful value to pass. I definitely agree on going
forward with the high res timer as first param.

Depending on performance.now's presence.. I'll likely recommend feature
detecting via:

if (duration < 1e12) /* high res timer */
else /* epoch timestamp */
