PointerEvent Interface

dictionary PointerEventInit : MouseEventInit {

	long pointerId = 0;
	double width = 1;
	double height = 1;
	float pressure = 0;
	float tangentialPressure = 0;
	long tiltX = 0;
	long tiltY = 0;
	long twist = 0;
	DOMString pointerType = "";
	boolean isPrimary = false;

};

[Constructor(DOMString type, optional PointerEventInit eventInitDict), Exposed=Window]

	interface PointerEvent : MouseEvent {
	readonly attribute long pointerId;
	readonly attribute double width;
	readonly attribute double height;
	readonly attribute float pressure;
	readonly attribute float tangentialPressure;
	readonly attribute long tiltX;
	readonly attribute long tiltY;
	readonly attribute long twist;
	readonly attribute DOMString pointerType;
	readonly attribute boolean isPrimary;

};
