3840e0b234 Cycles / Ray Depth: 
* Added a Ray Depth output to the Light Path node, which gives the user access to the current bounce.
This can be used to limit the maximum ray bounce on a per shader basis. Another use case is to restrict light influence with this, to have a lamp only contribute to the direct lighting.

This is part of my GSoC 2013 project. SVN merge of r58091 and r58772 from soc-2013-dingto.

e6a84eb1b5 Cycles: add light falloff node, with quadratic/linear/constant falloff and a 
smoothing factor to reduce high values near the light.
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Light_Falloff

Note that this was already possible to do manually with the Ray Length, but
this adds a convenient node for it. This commit also makes the mapping node
min/max option work, fixing #31348.

d64661b507 Cycles: add Ray Length output to Light Path node. This gives the distance travelled 
by the last light ray. One use case for this might be to do absorption.

Patch #31232 by Agustin benavidez, see this blog post for details:

df625253ac Cycles: 
* Add max diffuse/glossy/transmission bounces
* Add separate min/max for transparent depth
* Updated/added some presets that use these options
* Add ray visibility options for objects, to hide them from
  camera/diffuse/glossy/transmission/shadow rays
* Is singular ray output for light path node

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:
