Thomas Dinges 3840e0b234 Cycles / Ray Depth:
* Added a Ray Depth output to the Light Path node, which gives the user access to the current bounce.
This can be used to limit the maximum ray bounce on a per shader basis. Another use case is to restrict light influence with this, to have a lamp only contribute to the direct lighting.

This is part of my GSoC 2013 project. SVN merge of r58091 and r58772 from soc-2013-dingto.
