/**
* Draws the outline of the Figure bounds to make adjustment easier.
*
* @author Werner Randelshofer
* @version 3.0 2008-05-22 Added support for hover handle.
* <br>2.0 2008-05-11 Handle attributes are now retrieved from
* DrawingEditor.
* <br>1.2 2008-04-15 Distinguish between bounds handle for resizing
* and for transforming.
* <br>1.1 2008-04-12 Improve visibility of the outline, by drawing it
* using two differently colored strokes.
* <br>1.0 April 15, 2007 Created.
