        * gtk/gtkbutton.c (gtk_button_grab_broken): Handle broken
        grabs.

        * gtk/gtkrange.c (gtk_range_grab_broken): Handle broken
        grabs.

        * gdk/gdkevents.h: Add a boolean to specify wether the broken
        grab was implicit.

        * gdk/x11/gdkdisplay-x11.c (gdk_display_pointer_is_grabbed):
        As the documentation states, don't return TRUE for
        implicit grabs.

        * gdk/x11/gdkdisplay-x11.h (struct _GdkDisplayX11): Add
        a boolean field to store wether a pointer grab is implicit.

        * gdk/x11/gdkmain-x11.c (_gdk_xgrab_check_button_event):
        Track implicit grabs.

        * gdk/x11/gdkevents-x11.c (gdk_event_translate): Call
        _gdk_xgrab_check_button_event for button events.
