High CPU use after stopping the animation with size animation enabled

[martinflorek]

Calling stop() does not disable the animation fully and takes a lot of CPU. The stop method incorrectly calls start() instead of stop on the ballSizeAnimator:

  public void stop() {
    ballPathAnimator.stop();
    if (sizeAnimationEnabled) {
      ballSizeAnimator.start();
    }
  }

Can confirm this happens on my end as well.
