089abdecf7 Cycles: attempted fixes for OS X preview render problem, and disable 
kernel cache there now as well since it seems to give issues there.

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.

cfbd6cf154 Cycles: 
* OpenCL now only uses GPU/Accelerator devices, it's only confusing if CPU
  device is used, easy to enable in the code for debugging.
* OpenCL kernel binaries are now cached for faster startup after the first
  time compiling.
* CUDA kernels can now be compiled and cached at runtime if the CUDA toolkit
  is installed. This means that even if the build does not have CUDA enabled,
  it's still possible to use it as long as you install the toolkit.

6edb09fe93 Compile fixes for MinGW, checked with basic initial setup, no CUDA, gcc 4.5.2. 
OpenImageIO still gives link-time errors, will try to make a lib for MinGW, see if it is fixed.

1135875ab1 Cycles: 
* Fix crash in light path node
* Fix struct alignment issue for cuda
* Fix issue with instances taking up too much memory
* Fix issue with ray visibility working incorrect on some objects
* Enable OpenCL always and remove option, it has no dependencies so may as well
* Refuse to load kernel if OpenCL version < 1.1, recent drivers are needed
* Better error handling for OpenCL device
* 3D views with rendered draw mode will now revert to wireframe on file load

27102bfec4 Cycles: OpenCL library is now dynamically loaded so that blender doesn't crash 
if it's not installed on the system.

360fcd73fe Cycles: 
* add some (disabled) test code for using OpenImageIO in imbuf
* link cycles, openimageio and boost into blender instead of a shared library
* some cmakefile changes to simplify the code and follow conventions better
* this may solve running cycles problems on windows XP, or give a different
  and hopefully more useful 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:
