Revision: 50204
          http://projects.blender.org/scm/viewvc.php?view=rev&root=bf-blender&revision=50204
Author:   dingto
Date:     2012-08-25 16:52:55 +0000 (Sat, 25 Aug 2012)
Log Message:
-----------
Tomato Cycles:
* Added a Brick Texture Node to Cycles.
* Based on the Blender Internal Brick Texture with some modifications. 
* Tested on CPU and GPU (CUDA & OpenCL)

Documentation: http://wiki.blender.org/index.php/User:DingTo/CyclesBrickTexture

ToDo: Only works correct on flat surfaces, like a Plane. If you attach the shader to 3D objects like a cube, the mapping is not correct on the Y/Z vector. 

Thanks to Lukas Toenne for fixing a issue I had with the Node code! :)
