        * gtk/gtkrange.c (gtk_range_adjustment_value_changed): removed code
        that forced range repaints upon every motion event, because these tend
        to stall other repaints on busy CPUs.
        added a timer to still force repaints every once in a while (roughly
        5Hz atm) to avoid leaving the user without feedback on the range.
        fixes bug #460534.
