Did a quick and dirty implementation of a spatial hash structure to speedup RTAO, ray results are stored in cells indexed by pos/normal/cell size and after storing a few rays occlusion can be queried from the cell instead of raytracing it. 3x faster raytraced AO for that scene with no denoising.

Finally got around to adding something I've been meaning to add to the toy renderer for ages: mesh lods, courtesy of meshoptimizer github.com/zeux/meshopt....
