That works, but now it chokes on AGLPixmap...

... so I wonder if "AGLPixmap windowId;" should also be changed to  
"AGLPbuffer windowId;"?

Doing that works.  But I imagine that the rest of the nviz library  
must be changed to use AGLPbuffers.

I didn't get errors elsewhere about missing AGL pixmap functions.  I  
only see those in render.c, which I disabled to be able to compile  
libnviz.
