/**
* A DrawnRectangle which draws in 3D.<p>
*
* Drawn raised by default, drawing style used by paint() is
* controlled by raise() and inset(). Note that raise() and
* inset() do not result in anything being painted, but only set
* the state for the next call to paint(). To set the state and
* paint in one operation, use paintRaised() and paintInset().
* <p>
*
* The current state of the rectangle may be obtained by
* calling isRaised().<p>
