    Author:     Rik_Heywood (Xara Group Ltd) <camelotdev@xara.com>
    Created:    16/6/94
    Purpose:    This is the Ellipse shape. It is based on the NodeSimpleShape, which means
                that it is fitted into a parallelogram. It is actually made up of 4 bezier
                curve sections.
    SeeAlso:    NodeSimpleShape; NodeRect
