CanvasComponent, Figure, VisibleComponent, UserObjectContainer

public abstract class FigureWrapper
extends AbstractFigure

A FigureWrapper is a figure container that contains a single child figure. The purpose of a FigureWrapper is to provide an abstract superclass for application-specific figures, that need to implement certain behaviour but don't particularly care about their appearance.
