Detailed Description

Control over animation playback and values.

This class provide access to the values that control how an animation is played. This includes the minimum and maximum frames included in the playback, whether the playback loops, and whether the animation runs in all views, or only the active view, etc.

Methods also exist that mirror the functionality of the controls found on the time slider in the UI to start and stop the playback.
