This post processing effect implements this article to reconstruct normals from the depth buffer.
My goal is to learn more about shaders myself, and eventually I want to try my hand at outlines in a later PR.
It's in draft for now because it's kind of messy and I would love to get some feedback from @almarklein to learn what I could do to streamline this code.
For one thing, I don't fully get why the colors aren't stable when I rotate the camera. I am converting the normals to world space...
