Yeah, it seems mapview-relative coordinates would simplify things a
lot for widgets bound to map objects. I was doing the translation
manually, but with more widgets that would soon become cumbersome.

It would also solve the problem of widgets going out of sync with the
mapview once and for all.

I suppose it could be done with a bool variable in manager_child and a
mapview variable in window_manager. I'm not sure what would set the
latter - is changing mapviews managed by schedules?

Also, we'd need to consider, whether the mapview should be optional in
window_manager, so that it would still work in cases when there's no
mapview, like main menu. It would probably mean some kind of exception
should be returned when the user tries to add a mapview-relative
window when the mapview is not set.
