Return the current mouse position in coordinates relative to the upper left of the (main) screen.
Returns whether the mouse ever moved or it was just a click or long hold.
Synchronously track the mouse after a click until the mouse button is released again. Call us back whenever the mouse moves or the pressure changes. Button numbers are 0-based indexes: mouseButtonNumber == 0 is left, mouseButtonNumber == 1 is right, higher numbers mean other buttons. Coordinates are relative to the upper left of the (main) screen. If trackingHandler returns NO, tracking will be aborted.
