        * gdk/win32/gdkevents-win32.c:
        Refactored some of the window hiding/showing code from
        WM_ACTIVATE to WM_SIZE and WM_SYSCOMMAND.  Having this
        under WM_ACTIVATE was causing the application to go into
        a weird state when the user right-clicked on the taskbar
        entry of a window that was minimized.  (#505928)
