HALO: fix the integer division bug

    The newHeight is calculated by an integer division, which leads to an
    ugly bug. E.g. a 95x96 image will get a newHeight of 0 because
    (95 / 96 * 113) equals to 0. This will lead to a SystemUI FC.

    Fix it by multipling first and dividing afterwards.
