Cycles / Toon BSDF:
...
* Added a toon bsdf node to Cycles. This was already available as OSL only closure, but is now available inside the SVM backed as well, for CPU and GPU rendering.
* There are 2 variations available, diffuse and glossy toon, selectable via a menu inside the node.

Cycles: code refactoring to deduplicate the various BVH traversal variations.
...
Now there is a single BVH traversal code with #ifdefs for various features.
At runtime it will then select the appropriate variation to use depending if
instancing, hair or motion blur is in use.
This makes scenes without hair render a bit faster, especially after the
minimum width feature was added. It's not the most beautiful code, but we can't
use c++ templates and there were already 4 copies, adding 4 more to handle the
hair case separately would be too much.

Cycles Hair: Strand Minimum Pixel Size
...
Code is added to restrict the pixel size of strands in cycles. It works best with ribbon primitives and a preset for these is included. It uses distance dependent expansion of the strands and then stochastic strand removal to give a fading. To prevent a slowdown for triangle mesh objects in the BVH an extra visibility flag has been added. It is also only applied for camera rays.
The strand width settings are also changed, so that the particle size is not included in the width calculation. Instead there is a separate particle system parameter for width scaling.
