first pass on tattoo layering - 2 layers, 1 "base" layer which is fixed onto the player model, 1 which is edited during a painting session - tattoo compositor merges the editing layer onto the base layer when exiting the menu or saving - fade is applied to base layer, and baked into the png when merging downwards - rads add fade to the base layer visually with a parameter, which is only baked in during a merge - reworked to accomodate a separate player sending the tattoo edits to the other for saving (bc tattoo chair eventually) - moved more code to serverside to allow for direct painting communication between 2 clients
