 // An implementation of NativeWidget that binds to a ui::Window. Because Aura
 // is used extensively within Views code, this code uses aura and binds to the
 // ui::Window via a Mus-specific aura::WindowTreeHost impl. Because the root
 // aura::Window in a hierarchy is created without a delegate by the
 // aura::WindowTreeHost, we must create a child aura::Window in this class
 // (content_) and attach it to the root.
