Thomas Thurman 5dbe941495 defensive programming; check meta_screen_get_compositor_data() throughout
2008-06-05  Thomas Thurman  <tthurman@gnome.org>

        * src/compositor/compositor-xrender.c (paint_root, destroy_win,
        create_root_buffer, paint_windows, repair_screen, window_has_shadow,
        xrender_set_active_window, paint_dock_shadows, unmap_win, restack_win,
        make_shadow, resize_win, process_property_notify, free_win,
        process_configure_notify, process_circulate_notify, add_damage):
        defensive programming; check meta_screen_get_compositor_data()
        throughout in case it returns NULL.  In particular, when this
        happened in a certain situation in xrender_set_active_window
        this caused a segfault; refs #530702 (and LP#178953 has more data)
        but this doesn't close them.
