Is there any way to use a Picture Control so that the image (say, a sphere) is the only thing you see? In other words, don't show the borders of the control or its background? I know this can be done easilly using a transparent GIF image in an Image control but I need to use a Picture Control for 2 reasons.

1. Ability to use Circle, Line, etc, methods on it.
2. Picture Control can act as a container for other controls, while an image control can't.

Any suggestions?
