Paper and Canvas Simulation

Every few months someone seems to bring up a desire to simulate painting on a textured canvas or paper in Studio Artist. Of course there's a lot of different ways to do it, but sometimes it can be tricky to edit any arbitrary paint synthesizer preset to incorporate paper texturing without getting under the hood of the paint synthesizer. So i've recently been adding some new macro edit commands that let you perform high level edits on any paint synthesizer preset to add paper or canvas texturing.
