   Performer 2.0 does have a set of quaternion routines. However the
   interface to a DCS remains as before, so you have to create a matrix
   from your quaternion. This is reasonable, since GL uses a matrix.
   How useful would it be if we folded some quaternion functionality into
   pfDCS? It seems that would be mainly a convenience, albeit perhaps a
   significant one for quaternion users.

At one time someone (Mike Jones, I think) posted the 2.0 quaternion
interface here. Could you post it again?
