The incoming bounds describe the maximized size and position of the
window in the virtual coordinate system. But the window manager expects
that the bounds are based on the size of the primary monitor and
position is based on the actual window 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.
