This eliminates the O(N^2) (N = map leaf count) operation of finding visible lights and will later allow for finer culling of the lights as they can be tested against the leaf volume (which they currently are not as this was just getting things going). However, this has severely hurt ad_tears' performance (I suspect due to the extreme number of leafs), but the speed seems to be very steady. Hopefully, reconstructing the vis clusters will help (I imagine it will help in many places, not just lights).
