All Implemented Interfaces:

android.view.Choreographer.FrameCallback , java.lang.Cloneable
```
public class LottieValueAnimator
extends BaseLottieAnimator implements Choreographer.FrameCallback
                    
```
This is a slightly modified ValueAnimator that allows us to update start and end values easily optimizing for the fact that we know that it's a value animator with 2 floats.
