A simple B&W trimsheet masking node. There is an RGBA color verison as well. It takes 4 input textures, slices and stacks them into a 4 texture trimsheet. Sliders let you adjust the sizes of each trim texture. It uses only simple math to mask and add each texture to each other for the final trimsheet result. No scaling actions are taken.

Based on Rodzilla's prototype slicer, forked by Cat Prisbrey.
