area occupied by a screen or onscreen window, with respect to the origin (0,0)
of the desktop coordinate system. A secondary display screen will have its
top-left corner not at (0,0), but at a proper offset, depending if mirror mode

An onscreen window which is not displayed in fullscreen mode will have its
