cb4b5e12ab Cycles: Cleanup, spacing after preprocessor 
It is supposed to be two spaces before comment stating which if
else/endif statements corresponds to. Was mainly violated in the
header guards.

516e82a900 Code refactor: add ProjectionTransform separate from regular Transform. 
This is in preparation of making Transform affine only.

0579eaae1f Cycles: Make all #include statements relative to cycles source directory 
The idea is to make include statements more explicit and obvious where the
file is coming from, additionally reducing chance of wrong header being
picked up.

For example, it was not obvious whether bvh.h was refferring to builder
or traversal, whenter node.h is a generic graph node or a shader node
and cases like that.

Surely this might look obvious for the active developers, but after some
time of not touching the code it becomes less obvious where file is coming
from.

This was briefly mentioned in T50824 and seems @brecht is fine with such
explicitness, but need to agree with all active developers before committing
this.

Please note that this patch is lacking changes related on GPU/OpenCL
support. This will be solved if/when we all agree this is a good idea to move
forward.

1c5cceb7af Cycles: Move intersection math to own header file 
There are following benefits:

- Modifying intersection algorithm will not cause so much re-compilation.
- It works around header dependency hell and allows us to use vectorization
  types much easier in there.

dc1043dda0 Cycles: Add fast math function module 
It is based on fmath.h from OIIO and could be used to give some speedup
in areas where absolute accuracy is not so critical.

ee36e75b85 Cleanup: Fix Cycles Apache header. 
This was already mixed a bit, but the dot belongs there.

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:

* Sobol direction vectors from:
