Detailed Description

Unlike Java Swing's MouseListener, the Pen & Paper Click Handler cannot sense mouseover. Therefore, there is no analogue to mouseEntered, Exited.

This method does the hard work of figuring out when a pen pressed, released, and clicked.

It is up to the subclass to do something interesting with it once the events are triggered.

We also use the 20 ms filter heuristic that the InkCollector uses. We assume people can't click faster than 20ms.
