        Don't wireframe when accessibility is on, it apparently
        causes a desktop wide freeze.

        * src/prefs.[ch] (meta_prefs_init) (change_notify)
        (update_gnome_accessibility) (meta_preference_to_string)
        (meta_prefs_get_gnome_accessibility) : Add code to monitor
        accessibility status.

        * src/display.c (meta_display_begin_grab_op): Check
        accessibility status before going ahead with wireframe.
        Fixes #159538
