I can do outlines and it has a discontinuity threshold but no hidden
surface. Painter's - depth sorted drawing - is a possibility if the EPS
interpreter is sensible about its drawing order but true hidden surface
isn't trivial and it's unlikely I'll be going down that route anytime soon.
Swuff isn't dead but there's not been too much interest in it. I did offer
the source up for anyone who fancied it but there were no takers.
