Run an unminimize effect

Fri May 26 16:48:29 2006  Søren Sandmann  <sandmann@redhat.com>

        * src/effects.c (meta_effect_run_unminimize): Run an unminimize effect

        * src/window.c (meta_window_unminimize): Store a "was_minimized"
        boolean in the window.

        * src/window.c (meta_window_show): If the window was minimized,
        run an unminimize animation.

        * src/c-window.c (meta_comp_window_run_unminimize): Add an
        unminimize animation, running the minimize one in reverse.
