Impressive work! I'll do a detailed review in next weeks, but after a
quick look over the patch this looks all quite reasonable. If you have
specific questions about design or code now I can look into those
sooner and try to give feedback.

Regarding the multiple importance sampling of emissive hair, that's
not particularly important I would think, most of the time you'd want
to keep that disabled anyway. It's nice if it works, but hair is not
typically used as a light source of course.
