* https://android-developers.googleblog.com/2011/05/introducing-viewpropertyanimator.html
* The code above code creates three separate animations and plays them together in an AnimatorSet.
* This means that there is the processing overhead of setting up the AnimatorSet
* and running three Animators in parallel to animate these x/y/alpha properties.
* There is an alternative approach using PropertyValuesHolder that you can use to combine multiple properties inside of one single Animator:
