I want to draw use IRISGL to draw HUD symbols, in an ortho2 window, that
overlay Performer objects (ships and aircraft). How do I determine the
screen position of a Performer geometry node?

I'm using Performer 2.0, IRIX 5.3, IRISGL (not OPENGL), in a GL window (not
GLX). gluProject() might do it but needs OPENGL libraries and I don't
think I can link to OPENGL and IRISGL libraries at the same time.
