Tom, that refers to raytracing.  Tessellation is a separate step, one that's 
on the list but isn't (yet) at the top of the priority heap.

Roughly, the stages are:

1)  NURBS raytracing (what's available in the latest release)

2)  STEP import (pretty far along, being debugged)

3)  Basic NURBS editing (rotate, scale, translate - NOT surface manipulation, 
at this stage - basically what's needed to move NURBS around in MGED)

4)  STEP export

5)  NURBS tessellation

I should note there isn't much in the way of dependencies here - any of these 
tasks can be worked more or less independent of the others.  It's just a 
question of where resources get allocated, and right now step importing has 
priority (otherwise the only way to import NURBS is the 3dm-g path, which has 
its own issues - gotta have 'em in BRL-CAD before we can do much with 'em).
