Interesting. No, I do not need them. In the meantime, I have found there is 
also an os/2 port of Mesa. I'll try both and see which one is fastest. Mesa 3.2 
supports OpenGL 1.2.

I'll have a look tonite, thanks.

I need to make it as generic as possible, hence the use of OpenGL. Basically 
what I'm aiming at is a win32-OS/2-Linux.
Mind you, OpenGL is the first thing I thought about, but at this stage nothing 
is cast in stone yet.
Once the project develops, I might end up with a C program with a Tcl/Tk 
interface or something even totally different.
Or the whole thing could be cancelled, it is not, unfortunately, the first time 
this happens.

Thanks all the same, I'll get the articles for my general education anyway :-)
