 // LockLayoutManager is used for the windows created in LockScreenContainer.
 // For Chrome OS this includes out-of-box/login/lock/multi-profile login use
 // cases. LockScreenContainer does not use default work area definition.
 // By default work area is defined as display area minus shelf, docked windows
 // and minus virtual keyboard bounds.
 // For windows in LockScreenContainer work area is display area minus virtual
 // keyboard bounds (only if keyboard overscroll is disabled). If keyboard
 // overscroll is enabled then work area always equals to display area size since
 // virtual keyboard changes inner workspace of each WebContents.
 // For all windows in LockScreenContainer default wm::WindowState is replaced
 // with LockWindowState.
