as the black polygons (duh:) and not as nice looking as the sky dome, but also
not as slow (fps when standing in the normal coridor looking at the sky in
start: 26 for skydome, 37 for id skys, 44 for black). Good for when you want
to see sky other than black but your card can't handle the fillrate
requirements of skydome. I'll clean up the sqrt in there soonish.
r_local.h, r_shared.h, client.h and render.h at the same time (couldn't get
away from that:/) verly likely to be lots of breakage (eg, player and eye
models are NOT checksummed atm), but everything builds
