-// MultiAnimation is an animation that consists of a number of sub animations.
-// To create a MultiAnimation pass in the parts, invoke Start() and the delegate
-// is notified as the animation progresses. By default MultiAnimation runs until
-// Stop is invoked, see |set_continuous()| for details.

-  // the percented completed.
-  // end_time_ms: the end time used to calculate the percentange completed.
