 // a property of the embed root. When this happens WindowTree calls the
 // appropriate function on WindowManager. For example, if a
 // WindowTreeClient calls SetWindowBounds() on its embed root, WindowTree
 // calls WmSetBounds(). WindowManager can then decide if it wants to
 // change the bounds or not.
