Shadow Map Ray Tracing is a technique that ray cast against the shadow depth buffer. The technique is described in "Soft Shadows by Ray Tracing Multilayer Transparent Shadow Maps". Note that we only implement the single layer approach since storing multiple depth is prohibitively expensive. Pull Request: https://projects.blender.org/blender/blender/pulls/111809
