    ### we get the opposite of the scrolling amount
    ### vector (using the opposite is an usability measure,
    ### so the scrolling amount shows a number as if the
    ### screen had moved, when in fact it was the objects in
    ### the world which moved in the opposite direction) and
    ### map it to the int constructor

    return "({:>4}, {:>4})".format(*result)
Return custom formatted, scroll amount.
