Otherwise we could fail to validate the new configuration depending on
which output we're initializing mirror mode from.
gnome_rr_config_applicable() creates a temporary array of outputs for
validation and, in clone mode, all of them are assigned the same
geometry but, since it lacks context about which output the user is
currently on, it just uses the first one's geometry for all of
them. If this first output isn't the one the user is changing in the
UI then we never called _set_geometry() on it with a clone mode
geometry and thus the validation would fail because the geometry used
is that output's current mode which might not match the clone mode's.

It is possible to press the Add button in the custom shortcut dialog
when the name and command fields are empty. Disable the button by
default, and only enable it when the name and command is non-empty.

The call to nm_setting_connection_get_zone() returns a pointer to
memory that will be freed before the D-Bus reply handler is called.
Make sure to take a copy of the string, and free it when finished.

E.g. selecting a folder and then dismissing the dialog via the cancel
button or by pressing escape would still add the folder to the shared
folders list.
CcRRLabeler assumes an X11 session using override redirect toplevel
windows which are positioned in global desktop coordinates. Since this
isn't available on Wayland sessions, we're moving to a DBus API which
gnome-shell implements and works the same on both X11 an Wayland
sessions.
As side-effects, we get native looking gnome-shell OSD labels without
having to mimic the style ourselves and we're also now able to easily
show labels on mirrored setups.
