    gdkevents-win32.c: Disable configuration at minizing surfaces
    
    We want to temprarily stop the surface from being configured when it is
    minimized, so that when it is restored the surface will be in a
    consistent state.  Note that we are not explicitly enabling the
    forced configuration when restoring the underlying Win32 HWND as the
    the toplevel presentation will restore those for us when we make the
    surface visible again.
