  2. de-registering the RGB colors slightly (to imitate the phosphor arrangement); and
  3. superimposing a black grid pattern?
I already have a grid pattern generator function, made years ago (part of an attempt to recreate NTSC dot crawl artifacts). The grids are not exactly like the shader grids, but they might be close "enough."

I have no idea what SuperLumberjack is hoping to accomplish, but sign me up for your newsletter, because this is a seriously awesome filter. Even if you hate scanlines, you can blend it down a bit to minimize them; otherwise, it looks mindblowing on 4K.
