Cycles: different fix for perlin noise generating nan values, now check for
...
the result to be finite afterwards which is a bit faster and works for OSL
too without needing to slow down OSL itself.

Fix #30049 : cycles noise texture producing nan values with some
...
texture coordinates, due to int overflow.
Also minor tweak in shader code to avoid copying uninitialized
values, should have no effect though because they were not used.

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

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:
