        * gdk/win32/gdkevents-win32.c:
        * gdk/win32/gdkwindow-win32.c (show_window_recurse): Check if
        the window's state has GDK_WINDOW_STATE_MAXIMIZED set before
        calling ShowWindow (), and show using SW_SHOWMAXIMIZED or
        SW_RESTORE accordingly.  This fixes an issue where maximized
        windows that are iconified do not restore back to maximized
        when you click the taskbar. (#528975)
