Detailed Description

Event class for a touch manipulate event.

A manipulate event is sent when the user does a manipulation gesture with a touch screen. The manipulate event contains data like rotation amount, scale amount and pan amount, and the speed of change for them.

	ctrlKey	Flag that tells whether the control key is pressed.
	altKey	Flag that tells whether the alt key is pressed.
	shiftKey	Flag that tells whether the shift key is pressed.
	metaKey	Flag that tells whether the meta key is pressed.
	panX	Amount of pan done in X axis.
	panY	Amount of pan done in Y axis.
	panSpeedX	Speed of pan done in X axis (px/s).
	panSpeedY	Speed of pan done in Y axis (px/s).
