HWNDMessageHandler owns the WNDPROC, and is code that is shared with the non-Aura windows build. This code is in production and "should work."

On this diagram, the new classes are DesktopRootWindowHostWin(**) and DesktopNativeWidgetAura. DesktopNativeWidgetAura is a new views::NativeWidgetPrivate implementation that wraps an aura::Window* hosted in a special RootWindow/Host, which is implemented by DesktopRootWindowHost[Win|Linux].
