See also https://github.com/openpaperwork/paperwork/issues/548#issuecomment-383544821 Just to say that the screen resolution is not always the window size ;-) (Which is why I am so annoyed when Gtk applications like Evince get wider and wider each time…)

Actually, we can get both: screen resolutions + window size.
