Because the release is upcoming, and this code is much slower than the previous solution, I'm reverting.
Don't get me wrong here, your rectangle optimizer is a good thing, but it may not be well suited for use with the UHM.
You are welcome to put it back in again, together with a performance comparison that shows how it improves performance.

(If you want to check it yourself, spread 100 AKs across the map and walk them around and read the ReadMap::UpdateHeightMapUnsynced time profile. FYI the old code, because of the HeightMapUpdateFilter, uses virtually no CPU at all as long as the heightmap does not change, and this covers maybe 99.9% of all update requests.)
