forked from: forked from: Pseudo 3D Push Button Decorator

author Jesse Freeman aka @theFlashBum | http://jessefreeman.com

This is a simple demo of how to create a "3d Push Button" similar
to the new UI on wp7 phones. Noting fancy here but I do add the
notion of force so depending on where you press the button it will
rotate farther.

Since this is a decorator (see internal class) it can be applied
to any button (as long as you are compiling for FP 10.0).

It is important to note that the rotation will be "off" based on
the center position of the box.
