I am pretty sure the code is in the history, if you are patient enough
to look for it in git history. I can't remember why I re

It could, at least in principle. The underlying translate function is
called often enough that a slight different can be significant.

I am trying to replace an old code (biliteral filter) that rely on
ndimage.generic_filter with the neighborhood iterator. In the old code, the
generic_filter generates a contiguous copy of the neighborhood, thus the
(cython) code could use C loop to iterate over the neighbourhood copy. In the
