The coordinates of interface are modified according to the keyword arguments passed. The value of interface should be a top level interface. If a keyword is omitted then that part of the coordinates is not changed.
x and y are measured from the top-left of the screen rectangle representing the area of the primary monitor (the primary screen rectangle).
On Cocoa set-top-level-interface-geometry
behaves as if an interface toolbar is not present, even if
interface
does contain an interface toolbar.
