    Author:     Chris_Snook (Xara Group Ltd) <camelotdev@xara.com> (based upon DMc BevelTools class)
    Created:    9/2/2000
    Purpose:    Provides functionality for generating a list of AttrFillGeometry nodes.
                This class is used by the profiling function GetProfileFromSelection
                (virtual overide).

                And I'm fed up with explaining why this class exists, so here is a short
                and blunt explanation:

                "we have to do a couple of extra things, so its much better to have the
                functionality here than it is to go mucking up things as far as bevel nodes
                etc. are concerned.
