Calls the UI delegate's paint method, if the UI delegate is non-null.
We pass the delegate a copy of the Graphics object to protect the rest

Graphics.translate).
If you override this in a subclass you should not make permanent changes
to the passed in Graphics. For example, you should not alter the clip
Rectangle or modify the transform. If you need to do these operations
you may find it easier to create a new Graphics from the passed in
Graphics and manipulate it. Further, if you do not invoker super's
