ISSUE-3 (monotonic-clock): Animation frame times should be monotonically increasing [Request Animation Frame]

http://www.w3.org/2010/webperf/track/issues/3

Raised by: Cameron McCormack
On product: Request Animation Frame

Having animation frame times run off a monotonic clock would be better for authors than a clock that might jump backwards.  Doing this argues for the reinclusion of the Window.animationStartTime attribute, so that scripts can avoid using Date.now() to record the animation start time, which might bear little relation to the monotonic clock values anyway.
