Description:
Emitted when the gesture is recognized.
This means the number of touch sequences matches [property@Gtk.Gesture:n-points].
Note: These conditions may also happen when an extra touch (eg. a third touch on a 2-touches gesture) is lifted, in that situation
sequence won't pertain to the current set of active touches, so don't rely on this being true.
Parameters:
| sequence |
the `GdkEventSequence` that made the gesture to be recognized |
