Image stacking (focus stacking) Stacking cycles renders in the compositor?

There's a blog post going around about a plugin that uses ImageMagicImageMagick to stack Cycles renders together.

Why can't we do this in the compositor, and with a still frame?

  1. Is there a way to "get ahold of" the image that's in the buffer before it gets refreshed?

  2. Is there a way to average that image with the next refresh IN the compositor?

I've tried separating RGB, adding the components and dividing by two, and re-combining the RGB, but I think there's some clipping going on because that makes a very dark image.

It's relatively easy to animate the seed value, render a bunch of the same image, and average them together in GIMP, and that looks nice, but can we do this in the compositor and/or as we're rendering? I.e. average one sample with the previous one.
