  * This can be used to show an lottie animation in any place that would normally take a drawable.
- * If there are masks or mattes, then you MUST call {@link #recycleBitmaps()} when you are done
- * or else you will leak bitmaps.
- * <p>
- * It is preferable to use {@link com.airbnb.lottie.LottieAnimationView} when possible because it
