public class FXPinchSpreadTool extends AbstractTool<javafx.scene.Node>
FXPinchSpreadTool is an AbstractTool to handle
pinch/spread (zoom) interaction gestures.
The FXPinchSpreadTool handles the opening and closing of an
transaction operation via the FXDomain, to which it is adapted. It
controls that a single transaction operation is used for the complete
interaction, so all interaction results can be undone in a single undo step.
