e5f544dd92 Cycles: add transparent shadow support, i.e. shadows through Transparent BSDF 
shaders, enabled by default.

d5b679253a Cycles: 
* Sun, area and point lights with size now supported
* Cast shadow option to disable shadow casting for lamps
* Emission strength of materials tweaked such that setting strength to 1.0
  basically makes the material "shadeless" in that the value of the color
  input will be the resulting color in the image.

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.

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:
