Yea, I started playing with extinction as well, after having a conversation with
Peter (Popov) over ICQ. Setting it to 0 works, but makes the fade off of the white
media a bit crisp. Guess I'll play some more with the settings. It'd help to
understand the why's of this though. ie, why the media continues so strongly past
the fade_distance of the light source and why it's color inverts.
