Cycles, Eevee, OSL, Geo, Attribute Based on outdated refract patch D6619 by @cubic_sloth `refract` and `faceforward` are standard functions in GLSL, OSL and Godot shader languages. Adding these functions provides Blender shader artists access to these standard functions. Reviewed By: brecht Differential Revision: https://developer.blender.org/D10622
