TODO TODO
- will this change make much difference to the vips benchmark? - tried 8-bit data with a 32-bit intermediate, but it was only
slightly faster than C
- try a path with a 32-bit sum for larger matrices / scale / offset, 16-bit data would be even slower, no speed advantage
- make up a signed 8-bit code path? - make up a signed 8-bit code path?
- try a 16-bit path - make it more like morphology.c: have a param for the result of the
previous pass rather than a separate combining pass
