> * The GraphicalCompositeFigure adds to the {@link CompositeFigure CompositeFigure}
> * by containing a presentation figure by default which can not be removed. Normally,
> * the {@link CompositeFigure CompositeFigure} can not be seen without containing a figure
> * because it has no mechanism to draw itself. It instead relies on its contained
> * figures to draw themselves thereby giving the {@link CompositeFigure CompositeFigure} its
> * appearance. However, the GraphicalCompositeFigure's presentation figure
> * can draw itself even when the GraphicalCompositeFigure contains no other figures.
