 * This method animates a view at the end of a drag and drop animation.

 *        doesn't need to be a child of DragLayer.
 * @param to The final location of the view. Only the left and top parameters are used. This
 *        location doesn't account for scaling, and so should be centered about the desired
 *        final location (including scaling).
 * @param finalAlpha The final alpha of the view, in case we want it to fade as it animates.
 * @param finalScaleX The final scale of the view. The view is scaled about its center.
 * @param finalScaleY The final scale of the view. The view is scaled about its center.
 * @param duration The duration of the animation.
 * @param motionInterpolator The interpolator to use for the location of the view.
 * @param onCompleteRunnable Optional runnable to run on animation completion.
 * @param animationEndStyle Whether or not to fade out the view once the animation completes.
 *        {@link #ANIMATION_END_DISAPPEAR} or {@link #ANIMATION_END_REMAIN_VISIBLE}.
 * @param anchorView If not null, this represents the view which the animated view stays
