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: http://www.cs.columbia.edu/CAVE/software/softlib/dorf.php

Cycles: experimental OpenSubdiv code. This code can't actually be enabled for building and is incomplete, but it's here because we know we want to support this at some point and there's not much reason to have it in a separate branch if a simple #ifdef can disable it.

class SubdVert;
Cycles: remove approximate subdivision surface with gregory patches code. It was never fully implemented and will be replaced by OpenSubdiv. Only linear subdivision remains now. Also includes some refactoring in the split/dice code, adding a SubdParams struct to pass around parameters more easily.
