some gestures do not activate until a second gesture is registered

Description
I've noticed something odd with GtkGestureSwipe and GtkGesturePan when setting n-points to 3.
If I only have one gesture registered on the widget, it doesn't activate. But if I add a second gesture, such as GtkGestureScale or GtkGestureZoom, it will activate.
So for the time being, I'm just adding a dummy second gesture and it works as expected.
I tested this using the gesture demo in gtk3-demo and just #if 0 various gestures.
