forked from bartvdbraak/blender
Cycles / OSL:
* Add a few more OSL templates to the Text Editor, so people can use some of the OSL only shaders and closures. * Temperature (Kelvin) to RGB converter * Wavelength to RGB converter * Ramp closure (Phong and Diffuse) * Toon closure (Diffuse and Specular)
