Thanks, I'll check.

Extrapolating, SwapSides should not change any core variables, so
no exporter might know what side is actually shown.
--photo-flip- options do implement this approach, OTOH
I believe that the exporters that don't need some state values
e.g. layer colours or visibility are just free to ignore them;
there is nothing wrong in letting them read full state. probably there
is no strict rule.

Actually, I wrote it for batch GUI (in hid/batch/batch.c),
but then realised that exactly the same might be suitable for Kai-Martin
case, too (after renaming the action to avoid names conflict);
I just asked if it worked for him.

Certainly, it would be nice if there were single action for all,
though I'm not quite sure that I want HID interface to grow
in this particular case (which would mean another string
in every hid, while most of them will never use it) ---
I'm afraid it will become unreasonably long
some day. Just my impression which often is wrong.

I'll try to refactor the code if you think it's worth doing.
