public java.awt.geom.Rectangle2D.Double getDrawingArea()
Figure
The drawing area is used to inform DrawingView
about the
area that is needed to draw this figure.
The drawing area needs to be large enough, to take line width, line caps and other decorations into account that exceed the bounds of the Figure.

public void setBounds(java.awt.geom.Point2D.Double anchor, java.awt.geom.Point2D.Double lead)
Figure
This is used by Tool's which create a new Figure and by Tool's which connect a Figure to another Figure.
This is a basic operation which does not fire events. Use the following code sequence, if you need event firing:
figure.willChange(); figure.setBounds(...); figure.changed();

by the SelectAreaTracker and the HandleTracker to highlight figures, over which the mouse
pointer is hovering.
