Get some more wins for overall downrezzing and minimizing thrashing.

Also make sure that probes don't stamp - that creates thrashing when distant probes render.  We're at a low enough resolution on those things that higher mips are likely to go unnoticed, and we bake them frequently enough that we can pick up lower mips when we actually need them.
