This collection of event handlers is the most special of them all, as they want to unset any pointer/touch/stylus/keyboard/pad/etc focus, and handle events from a selected device/sequence combination through the MetaWaylandDragDest interfaces. The same interfaces also replace the MetaWaylandKeyboardGrabInterface in effect that handled DnD action changes. On the XDnD special grab side, we mainly need to let the current client (i.e. the drag source) keep receiving input events, as they drive the DnD operation from the X11 realm.
