A long press is a special form of click action; the default implementation uses a single signal with multiple states: query, action and cancel. On click we use the "query" state to check whether the ClutterClickAction supports long presses; if the callback returns TRUE then we install a timeout and we either emit the "activate" state when the timeout expires or we emit the "cancel" state if the pointer leaves the actor, or if the pointer moves outside a certain threshold. If the long press reached the "activate" state then we skip the clicked signal emission.
