A concrete implementation of ShapePair for general shapes and combination types. This class can represent the combination and perform basic operations like bounds, intersects and contains, but it cannot supply a PathIterator for the result of the combination. As a result the renderer will either have to be able to render the combination of two shapes directly or perform some other geometry computation of its own to achieve the subtraction or intersection. /**
