Thanks a lot! This was what I needed...

It works for me after changing dbuf in gui_init to start with GL_RGBA
and put the GLX_DOUBLEBUFFER at the end. Took me a couple minutes, and
comparing with glxdemo.c in Mesa 2.3...

First thing I did after that... I built a little rotating on top
(cam_?spin are there already, so...).  Wonderful, and so simple.

And if anyone has to add something that should be changed before
trying to use it in bigger project, go ahead.  It's
shameless-plug-time: I'll be using it in MARS, the Modelling Animation
and Rendering System.  Come to
http://members.tripod.com/~Juergen_Erhard/mars_index.html and check it
out...

Bye, J
