------- Additional Comments from vollick at chromium.org
Incorporates fixes for bugs I've found getting threaded animation in DRT.

Noteworthy changes
 - CCActiveAnimations need to keep track of their time offset. This is used
when resuming animations.
 - Suspend and Resume must cause the animation to pause at the given time and
prevent any run state changes.
