The wayland windowing backend emits such events for instance, so
have gestures cancel the sequence as those events get through.

If no match is found with the gesture widget when poking the event
window parents, bail out safely instead of falling in an infinite
loop. This was seen on Mutter.

Avoids sending spurious signals when an extra touch happens.

For now, at least. We do this by hiding the instance and
class structures in private headers.

This was missed because gtk_widget_remove_controller silently
does nothing on unowned controllers.

Quick-and-dirty patch to use a GtkGestureSingle for both
button press/release and touch event handling.

The utility of those signals is somewhat dubious now that there is
gtk_gesture_group(), so make that the only way to coordinate gestures.
The cooperation model offered by gtk_gesture_group() is flexible
enough,

This is replaced by GtkGestureLongPress, and all its callers have
been updated to use the replacement.
