2017 EDIT of an old deleted post...
OK, coming back to this thread in 2017, after a long hiatus.
(sorry guys, and [MENTION=79742]nenad[/MENTION], I started using a different email address. and no longer saw notifications)
I did learn a lot about frame geometry during this period, and know more now than I did then.
