20 /* The Idea is as follows:
+
21  * When the user add's a button we create a touch area for that region and wait for PEN_DOWN events.
+
22  * Once the user puts the pen down in this area we'll redraw the button with different shadows (feedback)
+
23  * and we'll now wait on PEN_UP or PEN_LEAVE events.
+
24  * If the user takes the pen away while in the area (PEN_UP), we call the provided user callback

25  * Otherwise (PEN_LEAVE) we only restore the initial shadows
