Diff updated on the SF tracker (

Formula adjusted to match proper definition of glow_radius, which also 
simplified it to the point where a lookup table shouldn't really have a 
significant speed advantage. Additive lighting also removed (waiting on 
a greater number of lighting levels). I don't see any reasons now why it 
can't get into CVS now, but I might be missing something.
