This patch moves some of the utility library shaders into a common directory and makes the necessary renames across shaders. Additionally, material-specific transform functions were moved outside of math utils into a separate transform_utils.glsl file. This is needed in preparation for the viewport compositor, which will make use of some of those utilities and will require all material specific bit to be removed out of those files.
