gtk/gdk/wayland/gdkdisplay-wayland.c
Carlos Garnacho cf8c3be030 gdk/wayland: Implement support for xdg-dialog Wayland protocol 
This protocol lifts some functionality from the gtk-shell protocol,
namely the ability to tag dialogs as modal. Ensure to use this
new protocol if available for the task, instead of the gtk-shell
protocol.
