Did you know Quake1/2/3/Unreal/etc have 7.1bit fixed point lightmaps? (I.E. their range is 0-2 mapped to 0-255 byte values)
Not much in the way of HDR, but it's something.
Regarding collision detection, you might be interested in model_brush.c in the DarkPlaces source code (glquake-derived engine that powers the standalone game Nexuiz and several other projects, besides
http://svn.icculus.org/twilight/trunk/darkplaces/model_brush.c?view=markup - do a search for TraceBox and you will find the Q1BSP/HLBSP and Q3BSP implementations of collision detection.
http://svn.icculus.org/twilight/trunk/darkplaces/collision.c?view=markup - this file contains all my brush collision code. (otherwise known as qhull, or "convex solid")
You can find more information about the engine at http://icculus.org/twilight/darkplaces/

Looks like you tried to load gfx.wad which contains only qpic images (hud imagery), you need the quake1.wad from the Q1Pack instead (which contains picmip images - mipmapped textures for maps).

Well that clearly needs to be fixed.

I don't know GTK+ at all, but if you wish to contribute a patch feel free :)
