[gtk+/wip/matthiasc/kill-event-signals: 80/123] Drop ::touch-event

[Matthias Clasen <matthiasc src gnome org>]

commit 73d107cf3bb7f5c9fc67cefd672f764a7ae04806
Author: Matthias Clasen <mclasen redhat com>

    Drop ::touch-event
    
    This signal is not used in GTK+, and has a suitable
    replacement with GtkGesture and its subclasses.
    
    If you need to catch the raw touch events, the generic ::event
    signal still works, too.
