 * This is an example of keeping track of individual touches across multiple
 * {@link android.view.MotionEvent}s.
 * <p>
 * This is illustrated by a View ({@link TouchDisplayView}) that responds to
 * touch events and draws coloured circles for each pointer, stores the last
 * positions of this pointer and draws them. This example shows the relationship
 * between MotionEvent indices, pointer identifiers and actions.
