/**
* A concrete implementation of {@link 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.
