Thanks for point out kurbo.

Another question(s): What is your opinion of Sederberg's CAGD publication? Has that publication had tangible mapping to your API designs? If so, what percentage of that publication (in your opinion) would be exposed as API in an ideal CAGD API?

I'm sure there's an art to what should be in an API and I have limited understanding of how the math maps to actual needed implementation.
