Carrying over a discussion on Slack, I'd like to request additive blending of surfaceshaders: ND_add_surfaceshader. This is not physically correct, but the intention would for use in NPR rendering.

At least for a naive implementation one could blend the BSDF and EDF components separately and join them into a new surfaceshader. Don't know if that's good enough though."
