If I remember correctly a GEGL operation has a way to tell what regions of the input data it needs in order to calculate a certain region of output data. A blur operation for example needs an input rectangle that is by about the blur radius larger than the output rectangle. Your fusion technique could probably tell that it always needs the all input data, regardless of the ROI.
