Thanks for the well thought out and quick replies!  I was at work when I
posted the question and later when I was at home I tried to reply after
rendering those samples... Unfortunately the webserver doesn't seem to
always like me and my high-latency connection (that's my guess anyway).  It
always prompts me for my login again after I type the correct password, or
tells me I typed the wrong password if in fact I did so.

Anyway, it looks like I probably will be storing the original control points
of the spline in an array afterall so that it can be modified in arbitrary
ways before use.

Thanks Mike.  I hadn't thought about this.

I hadn't realised that a transform could be pre-defined.  That sounds a lot
more convienient. Thanks

Actually I knew about this one... It's been very helpful for articulating
things!
