OneTouchScaleGestureRecognizerZoomSpeed Property

Additional multiplier for ScaleMultipliers. This will making scaling happen slower or faster. For this one finger scale gesture, this value is generally a small fraction, like 0.2 (the default). For a UI that starts 0,0 in the bottom left (like Unity), this value should be negative. For most other UI (0,0 in top left), this should be positive.
