[Bf-cycles] Would it be possible to implement CPU render for one layer and GPU for other?

[Marc Dion]

Sergey hinted a short while back that the AMD/Cycles OpenCL refactor is
going well.

Once the current mega-kernel design is removed and replaced with
mini-kernels which target specific critical loops, then multi-device
computing should quickly become fairly seamless and all system resources
can then be shared without one area of the machine becoming overloaded and
then causing everything else to fail. :(

Compared to other technology, heterogeneous computing is still in it's
infancy.   It will get there, and being patient in the mean time will help
us to get there with most of our hair still intact on our heads where it
should be. :)
