For now this only creates a degenerate bounding box hierarchy where all ops just have maximal bounds. I will flesh out FillBounds in future CL(s). Not quite sure why QuadTree and TileGrid aren't drawing right---haven't even looked at the diffs yet---so I've disabled those test modes for now. RTree seems fine, so that'll at least get us coverage for all this new plumbing.
