AnimationWithParentMixin<T> mixin
Implements most of the Animation interface by deferring its behavior to a given parent Animation.
To implement an Animation that is driven by a parent, it is only necessary
to mix in this class, implement parent, and implement T get value.
To define a mapping from values in the range 0..1, consider subclassing Tween instead.
