The NSToolTipOwner informal protocol declares a method that allows an object to dynamically provide the text to a tool tip. If the tool tip object does not implement this method, the NSObject protocol description method is invoked instead.

func view(NSView, stringForToolTip: NSToolTipTag, point: NSPoint, userData: UnsafeMutableRawPointer?)

Returns the tool tip string to be displayed due to the cursor pausing at location point within the tool tip rectangle identified by tag in the view view.
