Fix for a case of 'static initialization fiasco' with OSL closure variables. The parameter lists are using OIIO::TypeDesc static standards, which are also static variables. With static OSL libraries these are not initialized when the closure parameter lists are initialized, so OSL rejects the closure types.
...
Putting static initialization into functions works just as well, but ensures the OIIO::TypeDesc access is delayed until initialization is complete.

OSL Backend:
...
* Added the Phong BRDF from the inbuilt OSL shader library.
This can be used in OSL shaders only for now:
* phong(normal N, float exponent)
* phong_ramp(normal N, float exponent, color colors[8]

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:
