I do not really understand this argumentation, but this is not my main
interest.

It like to try some tweaks with fillborders filter, so I need some
16-bit per plane images for testing. Can you help me with that?

Another question is, why the fillborders doesn't check if the input is
writable, as suggested in doc/writing_filters.txt.
