nitpicker: Consider menubar for pointer reports

Browse Source 
The pointer-report facility used to report the screen-absolute position
of the mouse pointer. For nitpicker clients, however, this position is
meaningless because their coordinate is always constrained to the area
below the menu bar. This patch offsets the reported position
accordingly.
