Tool to scribble a BezierFigure

Version:

2.0.2 2009-03-15 Finish creation if the user switches to another view.
2.0.1 2008-06-08 FittedCurve did not include the point which was digitized on mouse pressed.
2.0 2008-05-17 Added support for property toolDoneAfterCreation. Draw rubberband while editing.
1.2 2007-11-30 Huw Jones: Factored calls to Bezier.fitBezierPath out into method calculateFittedPath.
1.1 2006-07-12 Werner Randelshofer: Extended support for subclassing.
