    }

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).

`type` | Event type.
`time` | Event time.
`flags` | Event flags.
`stage` | Event source stage.
`phase` | The current phase of the gesture.
`x` | The X coordinate of the pointer, relative to the stage.
`y` | The Y coordinate of the pointer, relative to the stage.
`dx` | Movement delta of the pinch focal point in the X axis.
