>   class NodeSimpleShape : public NodeRenderableInk

    Author:     Rik_Heywood (Xara Group Ltd) <camelotdev@xara.com>
    Created:    22/9/93
    Purpose:    A NodeSimpleShape is the base class for several primitive shapes that are
                bounded by a Parallelogram. This class contains 2 Pure Virtual functions that
                need to be re-written in base classes. These should be the only functions that
                need re-writting in most cases. They build a path for the shape given a
                bounding parallelogram.
