Cocoa : fix mouse cursor hang when RMB-dragging in a not frontmost window

With continuous grab on, in 2+ window setup, when RMB-dragging an object in a 3D view of a not active (not frontmost) window, mouse cursor was stuck, with no escape.
Cursor grab must be done by the window that is key (able to receive mouse move events).
