1. Denoise different channels (diffuse, specular, indirect) differently.
2. Make indirect bounce half res.

rt: add reflections
...
i was trying to add specular properly: replace them with specular bounce. but it doesn't really work that easily. need some kind of color mapping and figuring out how to make them look consistent.
this commit still does them separately, i.e. specular is done in direct lighting pass. no emissive is added on bounce. this probably makes it not reflect skybox ;_;.

Upload only dirty light clusters regions, PR #418
...
Ends up uploading only a few megs per frame, spread across a hundred or so ranges on average.
Still not great, now validation is too slow. But otherwise it's back to ~60fps.
I think it's end of the line for this approach. Even betterer light clusters would need a complete overhaul, e.g. being moved completely to GPU compute.
Fixes #385
