------- Additional Comments from vollick at chromium.org
Eliminated animation finished events. Animations will finish naturally on the
main thread and the final values will be set.

Animation started events are now also used to synchronize the main thread
animations' start times with their impl thread equivalents, preventing skew.
Until main thread animations receive their synchronized start times, they will
apply their initial values (i.e., they will be paused at time zero). This
guarantees that we will not jump to the animation's final value on the main
thread while we wait for the synchronized start time.
