FigureSubtree is a class that contains a sub-tree of the figure hierarchy. The contents of the set is not calculated until it is needed, to avoid duplicating large collections of objects.
BoundedSet is a class that contains figures that are bounded in some way by a rectangular region of a layer. It is designed to support efficient incremental drag-selection.
