The idea has been inspired by photoshop's effect layers, and the basic concept would be plugins that registers a new layer type. When sampled, the plugin is more or less simply executed, and the results are cached until any layer below the "programmable layer" has been modified. Layer modes and opacity are applied as if it was a normal layer, along with any layer mask.
You actually want even more,. you want to be able to group layers and apply an effect to the group, instead of all layers below. An extensive example with an upside down layer list (should actually be flippable by just using a proxying GtkTreeModel), where the entire image contents is generated using procedural plugins and effects is at:

And we want it rendered using glitz!

... but seriously, does anyone think it's possible to offload processing to the GPU? Is that part of the GEGL pipe goals? I didn't see anything at the site in the docs ...
