float RadiusX
(optional) The X radius of the touch in pixels. If not set, the default value of 25px will be used.
float RadiusY
(optional) The Y radius of the touch in pixels. If not set, the default value of 25px will be used.
float RotationAngle
(optional) The normalized pressure of the touch in the range of [0, 1].
int TouchID
ID of the touch. This value must be unique per touch but is shared by all events for the same touch (i.e. the Start, Move, and End events for a single touch share the same TouchID). This can be any number except -1, and a maximum of 16 concurrent touches are tracked.
TouchEventType Type
The touch event type. Touches begin with one TouchEventType.Start event, followed by zero or more TouchEventType.Move events, and finally one TouchEventType.End or TouchEventType.Cancel event.
