        * gdk/x11/gdkgc-x11.c gdk/x11/gdkprivate-x11.h: Keep
        track of when we have a clip mask set for the GC,
        and when we unset it, or switch to a clip region,
        immediately call XSetClipMask (..., None) to avoid
        Xlib caching stale data. (#111806)

        * gtk/gtktextdisplay.c: Don't set a clip mask
        when drawing alpha pixmaps; it isn't necessary any more.
