e731ffb648 Cycles: Oren-Nayar BSDF support. This is not a separate shader node, rather it
is available through the Roughness input on the Diffuse BSDF.
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Shaders#Diffuse

Patch by Yasuhiro Fujii, thanks!

cdee3435c6 Cycles: internal changes that should have no effect on user level yet, added
shader flags for various purposes, and some code for light types other than
points.

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.

db1664ed4c Cycles:
* Compute MD5 hash to deal with nvidia opencl compiler cache not recognizing
  changes in #included files, makes it possible to do kernel compile only
  once and remember it for the next time blender is started.
* Kernel tweak to compile with ATI/linux. Enabling any more functionality than
  simple clay render still chokes the compiler though, without a specific error
  message ..

da376e0237 Cycles render engine, initial commit. This is the engine itself, blender modifications and build instructions will follow later.
Cycles uses code from some great open source projects, many thanks them:

* BVH building and traversal code from NVidia's "Understanding the Efficiency of Ray Traversal on GPUs":
http://code.google.com/p/understanding-the-efficiency-of-ray-traversal-on-gpus/
* Open Shading Language for a large part of the shading system:
http://code.google.com/p/openshadinglanguage/
* Blender for procedural textures and a few other nodes.
* Approximate Catmull Clark subdivision from NVidia Mesh tools:
http://code.google.com/p/nvidia-mesh-tools/
* Sobol direction vectors from:
http://web.maths.unsw.edu.au/~fkuo/sobol/
* Film response functions from:
