/**
* A DrawnRectangle that draws an etched border.<p>
*
* Drawn etched in by default, drawing style used by paint() is
* controlled by etchedIn() and etchedOut(). Note that
* etchedIn() and etchedOut() 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
* paintEtchedIn() and paintEtchedOut().<p>
*
* Although it is permissible to set the thickness of
* EtchedRectangles, they tend to loose the etching effect
* if thickness is greater than 4.<p>
*
* The current state of the rectangle may be obtained by
* calling isEtchedIn().
