Composite operations do exist, in GEGL they are called
meta-operations, some examples are gegl:unsharp-mask, gegl:dropshadow
and gegl:difference-of-gaussians. It would also be possible, though
more cumbersome, to run a GEGL graph as part of the implementation of
a GEGL operation; off-hand I am not sure of such an example.
