Ok, it's been a long time since I've said anything, so I just want to let you all know that this project is still going very well. I'm hoping to release the next version over the next few days.
BTW, I'm working on fog right now, but I'm having some trouble with glide. It's giving me very non-interpolated fog, I'm assuming because the w coordinate is like 10000, and the precision isn't very good there. I was going to try fog coordinates, but when I put in the GR_PARAM_FOG_EXT, it wouldn't draw many objects anymore!
