This was already mixed a bit, but the dot belongs there.

c3e1fce775 Cycles: add Object Info node, with outputs object location, object/material
pass index, and a random number unique to the instance of the object.

This can be useful to give some variation to a single material assigned to
multiple instances, either manually controlled through the object index, based
on the object location, or randomized for each instance.

fb56dbc2af Cycles: procedural texture nodes reorganization. This will break existing files
using them, but rather do it now that I have the chance still. Highlights:

* Wood and Marble merged into a single Wave texture
* Clouds + Distorted Noise merged into new Noise node
* Blend renamed to Gradient
* Stucci removed, was mostly useful for old bump
* Noise removed, will come back later, didn't actually work yet
* Depth setting is now Detail socket, which accepts float values
* Scale socket instead of Size socket

for this but I've implemented it differently.

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:

* Sobol direction vectors from:
