The incoming bounds describe the maximized size and position of the window on the monitor that displays the window. But the window manager expects that the bounds are based on the size and position of the primary monitor, even if the window ultimately maximizes onto a secondary monitor. And the window manager adjusts these values to compensate for differences between the primary monitor and the monitor that displays the window. The method translates the incoming bounds to the values acceptable by the window manager. For more details, please refer to 6699851.
