	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.
