blender/intern/cycles/kernel/svm/svm_bsdf.h
Brecht Van Lommel ebc653463d Cycles: 
* Fix missing update when editing objects with emission materials.
* Fix preview pass rendering set to 1 not showing full resolution.
* Fix CUDA runtime compiling failing due to missing cache directory.
* Use settings from first render layer for visibility and material override.

And a bunch of incomplete and still disabled code mostly related to closure
sampling.
