OpenGL 2.0

I noticed that since upgrading to Gutsy I appear to have OpenGL 2.0 support callable from Python... Since I've never done any OpenGL 2.0 and I have the Orange Book sitting beside my I should give it a try.

After hacking the installed libraries I got the early result of the shaders in the picture which shows hemispherical lighting (not possible in OpenGL 1).

It all seems to work quite well. I was working on some cell shading but changing shaders while drawing the scene makes everything go black. I hope it's not a driver/binding issue but something I'm doing wrong (can't work it out yet though). Hopefully sometime in the future there will be fluffy chess pieces too :)

As for putting this into glChess I think this one will have to be handled very carefully. There is enough bugs from differing OpenGL setups (and broken drivers) that the code will have to be very robust. When things start working better I'll add a secret gconf key that turns on the shaders for those in the know...
