The hotSpot method returns the location of the point within the cursor image that represents where the mouse is onscreen. Effectively it controls where the 2D image of the cursor is drawn relative to the point that is the mouse's current location.

Well, part of what you should take away from that is that I've been operating on too little sleep this week and got two different NSEvent methods confused as a result.
You don't need to have an NSEvent instance for mouseLocation. You do for locationInWindow.
