GEGL is (as I understand it) actually a bit fancier than this.

It's a demand-driven system, so filters are never really rendered at
all. Instead, it just generates the pixels necessary to update the
display. From the users point of view, all filters apply instantly,
though more expensive filters will repaint the screen more slowly.
