Gets or sets a value that specifies whether the animation's value accumulates when it repeats.
Assembly: PresentationCore (in PresentationCore.dll)
When this property is set to true, the animation's output values only accumulate when the animation's RepeatBehavior property causes it to repeat its simple duration. It does not accumulate its values when it restarts because its parent repeated or because its clock was restarted from a Begin call.
