    #i125020# fix rounding error in AquaSalGraphics::RefreshRect()
    
    Rounding left and width down can accumulate a rounding error of almost two in
    the calculation of right. The existing code compensates for this by increasing
    the width by two, but since left has been decremented by one to accommodate for
    antialiasing artifacts this compensation is one to few by itself and two to few
    when accounting for antialiasing artifacts on the right. Y-pos and height have
    the same problems and get the matching fix.
