I have no strong opinion here. I know most filters (light, turbulence, gaussian blur, morphology, convolve matrix, displacement) will never be hw accelerated except the simplest ones (offset, merge). And yeah, we can have 3 results for each filters, although the filter itself only creates one, and the others are created on demand. But you should decide whether it is worth to work on this project. That is why I submit conceptual patches, since if this is not a good idea, at least I don't have to spend full days working on it.
