Used for touchpad pinch gesture events.
The current state of the gesture will be determined by the phase
field.
Each event with phase CLUTTER_TOUCHPAD_GESTURE_PHASE_BEGIN
will report a scale
of 1.0, all later phases in the gesture
report the current scale relative to the initial 1.0 value
(eg. 0.5 being half the size, 2.0 twice as big).4
