This was actually one of the first bugs (I am assuming it is a bug) that we
came across when starting out on the Yaroze.

By a bizarre coincidence the first program I wrote attempted to create a
single gouraud quad.  Of course it didn't work no matter what I tried.  I
went over every inch of the code for a whole day before deciding to try and
change the primitive type which did work (gouraud triangle from memory I
think).

Even gouraud quads in TMDs created by RSDLink don't seem to work.

Has anybody got a gouraud quad to work, or is this a bug?
