The RectangleFigure class

The RectangleFigure class holds a rectangle, which can be filled or unfilled. The user can modify it by grabbing one of its four corners. The DrawRectangle class overrides most of the methods of the DrawFigure class.

One difference compared to the line and arrow cases is that a rectangle is two-dimensional and can be filled or unfilled. The Fillable method returns True and the IsFilled and Fill methods are overridden. When the user double-clicks on a rectangle it will be toggled between the filled and unfilled states.
