We want to coalesce multiple touch events into the same wl_touch.frame event. Instead of poking internals to peek the touch events (and their slots) coming at us before we handle them, simplify things by queueing the event at a slightly lower priority than events, so we are ensured to handle all pending input events before sending the event. If there's no pending events, we can just send the frame event. As it doesn't make sense to hold any longer. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1486
