Update: add ability to step through higher levels of mip chain to reconfirm visibility
- controlled via culling.extralodsteps, default to 0 (same as before)
Out HiZ downsampling filter erodes depth at edges of objects, so if objects picks a low mip, there's a good chance it won't see any occluding depth
Tests: ran around apartments monument in editor with 0, 2 and 7. at 2 saved only 0.25% percent of drawcalls, but 7 can save up to 10% (will profile standalone later)
Update: draw picked hiz lod for occludees in occlusion debug
Tests: used debug visualization in editor
