Oh?  Now I'm puzzled.  Maybe Dave checked in those files himself.

I'll check *carefully* before I mess with it.

Absolutely...but since it's a CVS and can potentially be changed
right up to the last 10 seconds before I make an official 1.2
release out of it - I need to be sure that everyone can agree on
a short-term "feature" freeze while the last few wrinkles are
ironed out.

Yes - I was using it to view the plans of my house in PPE!
(Our architect kindly provided the CAD files)  I need to get
PPE's extrude code working so I can turn them into a 3D model :-)

Yes - it shows up in a few places in my Tux game too.

I think these are all symptoms of the same problem.

The problem is that all these cases are too complex to track down
what's going on.  I really need to write some stand-alone OpenGL
programs that do essentially what I think SSG is doing and see
if those work.  That'll help me to see if I have a misunderstanding
of the OpenGL Spec, or if one or more implementations are broken,
or whether there is a simple bug in SSG such that it isn't doing
what I think it is.

The glColorMaterial API isn't all that well described and quite a
few of the OpenGL Guru's out there cannot agree on what it's *supposed*
to do under some of the situations that can arise in SSG.  If the
guys who wrote the OpenGL spec can't agree then there is little chance
of all the implementations out there getting it right.

As always, if Quake doesn't use it - all bets are off.
