I am resetting it. I am pretty sure this code is OK - when I measure with
a stopwatch, I get the same timing.

Good advice, I will try it!

I have no problem giving you a copy of the code, but it is not in a state
suited for distribution and pretty embarrising. If you want to have a
look, you can download

It needs a working GL/GLU (preferable accelerated) and a linux system. It
