383bd34111 Fix T42021: OSL doesn't work when there are non-ascii chars in the path
Quite annoying, the same thing we do from the blender side, But as a positive
side we can get rid of some utf8/utf16 conversions.

Hopefully it all work fine now, at leats works on mu russki windoze laptop.

d980c3eccb Further fix for T37817: non-ascii paths fix in Cycles broke OSL rendering.
Not quite sure yet what is going on here, but this works for me.

114284b1fb creation of path from std::string on Windows (VC10/11/12) crashes (access error)
Summary:
Seems to be a known problem in boost: https://svn.boost.org/trac/boost/ticket/6320

Applied the solution but do not know if this is the right place.

4bdb54a76e Cycles OpenCL: patch #35514 by Doug Gale
* Support using devices from all OpenCL platforms, so that you can use e.g. both
  Intel and NVidia OpenCL implementations if you have them installed.
* Fix compile error due to missing fmodf after recent math node change.
* Enable advanced shading for Intel OpenCL.
* CYCLES_OPENCL_DEBUG environment variable for generating debug symbols so you
  can debug with gdb. This crashes the compiler with Intel OpenCL on Linux though.
  To make this work the preprocessed kernel source code is written out, as gdb
  needs this.
* Show OpenCL compiler warnings even if the build succeeded.
* Some small fixes to initialize cdDevice to NULL, add missing NULL check when
  creating buffer and add missing space at end of build options for Apple OpenCL.
* Fix crash with multi device + opencl, now e.g. CPU + GPU render should work.

I did a few tweaks to the code and also:

* Fix viewport render failing sometimes with Apple CPU OpenCL, was not taking
  workgroup size limits into account properly.
* Add compile error when advanced shading in the Blender binary and OpenCL kernel
  are not in sync.

eb87529e23 Cycles OSL: shader script node
Documentation here:
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/OSL
http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.65/Cycles

These changes require an OSL build from this repository:
https://github.com/DingTo/OpenShadingLanguage

The lib/ OSL has not been updated yet, so you might want to keep OSL disabled
until that is done.

Still todo:
* Auto update for external .osl files not working currently, press update manually
* Node could indicate better when a refresh is needed
* Attributes like UV or generated coordinates may be missing when requested from
  an OSL shader, need a way to request them to be loaded by cycles
* Expose string, enum and other non-socket parameters
* Scons build support

Thanks to Thomas, Lukas and Dalai for the implementation.

a87051bd8e Patch #32074: Fix compilation with boost 1.50
This patch switches from boost's filesystem v2 to v3.

This should be completely smooth due to filesystem v3 is pretty
old already.

eb2baf9abc Fix #29274: problem compiling cycles opencl kernel from directory with spaces.
Some drivers don't support passing include paths with spaces in them, nor does
the opencl spec specify anything about how to quote/escape such paths, so for
now we just resolved #includes ourselves. Alternative would have been to use c
preprocessor, but this also resolves all #ifdefs, which we do not want.

ebc653463d Cycles:
* Fix missing update when editing objects with emission materials.
* Fix preview pass rendering set to 1 not showing full resolution.
* Fix CUDA runtime compiling failing due to missing cache directory.
* Use settings from first render layer for visibility and material override.

And a bunch of incomplete and still disabled code mostly related to closure
sampling.

cfbd6cf154 Cycles:
* OpenCL now only uses GPU/Accelerator devices, it's only confusing if CPU
  device is used, easy to enable in the code for debugging.
* OpenCL kernel binaries are now cached for faster startup after the first
  time compiling.
* CUDA kernels can now be compiled and cached at runtime if the CUDA toolkit
  is installed. This means that even if the build does not have CUDA enabled,
  it's still possible to use it as long as you install the toolkit.

db1664ed4c Cycles:
* Compute MD5 hash to deal with nvidia opencl compiler cache not recognizing
  changes in #included files, makes it possible to do kernel compile only
  once and remember it for the next time blender is started.
* Kernel tweak to compile with ATI/linux. Enabling any more functionality than
  simple clay render still chokes the compiler though, without a specific error
  message ..

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:
