public class LottieViewAnimator
extends java.lang.Object
Animated a view based on a null layer. To use this, set a tag on your view with the key R.id#lottie_layer_name
and the value as the null layer name from After Effects.
This supports position, scale, rotation, and anchor point (pivot)
Positions will all be relative to the initial point. This is for the ease of use of the animator.
Without subtracting the initial position, animators would have to work with the animation in the
top left corner of the composition.
Anchor points affect the pivot point of the animation and should be set between 0 and 1.
Those values will be multiplied by the laid out width and height of the view.
For example, setting the anchor to (1, 1) would set the pivot to the bottom right.
