What's the simplest path for getting a pixel shader going for postprocessing? This is one of the "selling points" of SFML which was capable of some startling effects even a few years ago.

You have to render to a frame buffer or texture and then pass that into a second shader and render a quad that does the processing. The setup is somewhat complicated.

I really wish someone could put together a tutorial. This is something I've also wanted to know how to do for a long time but was never abled to figure it out.
