-// 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.
