[Bf-cycles] Branched PT + Correlated Multi-Jitter & MIS on Background increase rendertimes tremendously!

[Sergey Sharybin]

Here's a really quick patch which seems to make CMJ really close to Sobol
on my computer now: http://www.pasteall.org/56937/diff

Can't commit it to master because it's quite dangerous change (using fast
sqrt might backfire in some scenes), but if someone can compile blender
could confirm performance improvements that'd be cool :)
