| NSTrackingAssumeInside | The first event is generated when the cursor leaves the tracking area, regardless if the cursor is inside the area when the NSTrackingArea is added to a view.

| NSTrackingEnabledDuringMouseDrag | The owner receives NSMouseEntered events when the mouse cursor is dragged into the tracking area.
