Luke, I thank you for your help and for the answers you have provided.

BTW, the reason I used the inheritance trick was to be able to simply
typecast a GeometryPath * into a _GeometryRing *, etc. I understand that
some may frown at the practice.

Anyone else that may be able to answer my previous questions?

Bill
