Title: Implemented dual PGraphics spray mechanics

We are now drawing the spray twice (once for the paint screen and once for the wall screen) instead of mirroring the same PGraphics. This was necessary because the background transparency trick didn't work properly with shaders. Since we are only computing and drawing each point only once, the overhead of rendering two strokes instead of one is negligible.
