with FloatCanvas

To initialize:
RubberBandBox(Canvas, CallBack)
Canvas: the FloatCanvas you want the Rubber band box to be used on
CallBack: is the method you want called when the mouse is
released. That method will be called, passing in a rect
parameter, where rect is: (Point, WH) of the rect in
world coords.
Tol: The tolerance for the smallest rectangle allowed. defaults
to 5. In pixels
Methods:
Enable() : Enables the Rubber Band Box (Binds the events)
Disable() : Enables the Rubber Band Box (Unbinds the events)
Attributes:
CallBack: The callback function, if it's replaced you need to
call Enable() again.
