Sergey Sharybin 527d049c5c Cycles: Make camera-in-volume an official feature
This means it's no longer needed to enable experimental feature set in order to
have proper camera in volume support. And this also means if there's something
wrong going on, or if there's speed regression for cases when camera is obviously
not in the volume -- this issues are to be reported and handled in the regular
matter.

Happy blending!
