-[NSCursor hotSpot] tells you nothing about the mouse position. The hotSpot is
the location inside the cursor image of the tip of the arrow.
If you need the mouse position at the time of some event, use -[NSEvent
locationInWindow].
If you need the mouse position "now" inside some window, use -[NSWindow
mouseLocationOutsideOfEventStream].
If you need the mouse position "now" with neither an event nor a window, use
+[NSEvent mouseLocation].
