 * Returns an Animator which can animate a clipping circle.

 * Any shadow cast by the View will respect the circular clip from this animator.
 * <p/>
 * Only a single non-rectangular clip can be applied on a View at any time.
 * Views clipped by a circular reveal animation take priority over
 * {@link View#setClipToOutline(boolean) View Outline clipping}.
 * <p/>
 * Note that the animation returned here is a one-shot animation. It cannot
 * be re-used, and once started it cannot be paused or resumed.
 *
 * @param view        The View will be clipped to the animating circle.
 * @param centerX     The x coordinate of the center of the animating circle.
 * @param centerY     The y coordinate of the center of the animating circle.
 * @param startRadius The starting radius of the animating circle.
 * @param endRadius   The ending radius of the animating circle.
