Intermittent Lighting Change

See the following. Very reproducible just past the kitchen on the way to marine HQ.

Yeah this happens when the interpolation triangle flips between 4 nearest env_probes.
The current implementation is very simple where I just look for the 3 nearest env_probes and trilerp between them. I never got around to do a full implementation of #497.

I wanted to it similar like in Rage however Rage does it interpolate over time so it is not so sudden.

I haven't addressed this issue yet because it's not apparent if you shoot monsters.
