/**
 * 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>
