Replacing Quake2's RecursiveLightPoint with DarkPlaces'

It can also be applied to the software renderer as well.

I have seen a strange issue with flag models in some maps in Paintball2 after using this. They will be dark at spawn, but if I pick up the flag and drop it, it's fine. I tried moving the starting point for the light trace up a little, as I thought the flag may be spawning slightly in the ground, but that didn't appear to fix it. I'll have to investigate further. I'm wondering if the flag spawn is exactly on a brush split or something causing this oddity.

I've tracked down the issue and posted a reply in the thread you linked. In short, it's because the entities are exactly on the edge of the lightmap. I've modified the code with a simple tweak that fixes that particular issue, but it may result in others (haven't seen any yet).

Updated with another fix for negative values being returned.
