I had a suspicion that the problem might be my forcing antialiasing on 
globally using nvidia-settings. This has adversely affected my own code 
(OCaml, nothing to do with HOpenGL). But I tried turning it back off and the 
ShadowMap.hs demo still displays only a black screen here. I'm on Linux with 
a GF7900GX but it shouldn't make any difference.

As long as it works on someone else's computer, I'll keep fiddling with it 
here. Thanks!

BTW, the other OpenGL demos I've seen are fantastic - great work!
