* Applying Dahlia's interim path curve patch. it adds initial support for some tori/ring parameters. Thanks Dahlia!

* Some situations do not match the client's render of the tori, we know and are working on it.   This is an initial support patch, so expect it to not be exact.
* Some tapers are acting slightly odd.  Will fix.
