Cycles: color space control for image/environment texture nodes. Ideally would

be automated but need to think about how to do this, not so simply in a node
system. But guideline for now is, for color textures set to sRGB, for things like
bump or roughness map, set to Linear.

Blender modifications for Cycles integration.
...
Some notes about code status:
* The Blender modifications were fairly quickly put together, much more code
polish and work is needed to get this to a state where it can be committed
to trunk. Files created with this version may not work in future versions.
* Only simple path tracing is supported currently, but we intend to provide
finer control, and more options where it makes sense.
* For GPU rendering, only CUDA works currently. The intention is to have the
same kernel code compile for C++/OpenCL/CUDA, some more work is needed to
get OpenCL functional.
* There are two shading backends: GPU compatible and Open Shading Language.
Unfortunately, OSL only runs on the CPU currently, getting this to run on
the GPU would be a major undertaking, and is unlikely to be supported soon.
Additionally, it's not possible yet to write custom OSL shaders.
* There is some code for adaptive subdivision and displacement, but it's far
from finished. The intention is to eventually have a nice unified bump and
displacement system.
* The code currently has a number of fairly heavy dependencies: Boost,
OpenImageIO, GLEW, GLUT, and optionally OSL, Partio. This makes it difficult
to compile, we'll try to eliminate some, it may take a while before it
becomes easy to compile this.

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:
