Note, that this is legal behaviour for a SANE backend. It is not
recommended, though.
The reason is, that options can influence the available range or stepping of
other options.
It should generally be handled in a benign way in the backend, that is, the
backend should not needlessly reset already set parameters, but rather try
to match them to the new constraints as good as it can.
