backend-wayland & kiosk-shell: Missing fullscreen resize
This is a follow-up task/issue as a continuation from #420 (closed), which requires a couple of changes (at least the ones that I'm aware of -- so it might need more investigation) to work out correctly:
implement resizing of the parent surface, as the parent wayland back-end sends a configure event and the client ignores it -- this includes removing client-side decoration and implement fullscreen resize (see
sprawlwhen starting it)
handle output resizing (some related work that has been done !480).
