Sorry, but I'm not as confused as it may look. My provider has serious
mail problems and I'm still missing hundreds of mails. For example,
Erik's eMail about the DLists didn't arrive here and I though the whole
thread was about the crease patch.

The crease patch seems OK and an almost dramatic performance improvement.
There's only the 3D adf instrument.

I looked up Erik's patch in the mail archive and tried that as well.
It segfaults here, too.

nVidia's libGL doesn't seem to like glGenLists(1).
