131de4352b Cycles: fixes to make CUDA 4.2 work, compiling gave errors in shadows and
other places, was mainly due to instancing not working, but also found
issues in procedural textures.

The problem was with --use_fast_math, this seems to now have way lower
precision for some operations. Disabled this flag and selectively use
fast math functions. Did not find performance regression on GTX 460 after
doing this.

022d12a721 Fix most of #31307: cycles panorama camera not working correct with speed
vectors and window texture coordinates. Only for Fisheye Equisolid it's
still not working correct yet. Patch from Dalai with modifications.

1e2afcddd3 Fix #31168: cycles mask layer should only affect objects for camera rays.
Fix: texture coordinate normal output was not correct, still changed under
object transform.

1d8c798188 Cycles: support for motion vector and UV passes.
Most of the changes are related to adding support for motion data throughout
the code. There's some code for actual camera/object motion blur raytracing
but it's unfinished (it badly slows down the raytracing kernel even when the
option is turned off), so that code it disabled still.

Motion vector export from Blender tries to avoid computing derived meshes
when the mesh does not have a deforming modifier, and it also won't store
motion vectors for every vertex if only the object or camera is moving.

67030aaf84 Cycles: optimizations for instances in scene updates before render starts,
should load a non-trivial mesh instanced many times quite a bit faster now.

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:
http://code.google.com/p/nvidia-mesh-tools/
* Sobol direction vectors from:
http://web.maths.unsw.edu.au/~fkuo/sobol/
* Film response functions from:
