Gesture.connectBegin

Connect to Begin signal.

Emitted when the gesture is recognized.

This means the number of touch sequences matches propertyGtk.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.
