    <p>Hi Juha-Pekka,<br>
    </p>
    <p>The new test added do cover the gap of having multiple-plane
      rotation together, along with the top and bottom cropping
      scenarios. <br>
    </p>
    <p>The test work well for square figures i.e. the width = height
      =512, but for rectangular figure, the test needs some fix in
      get_multiplane_crc(), as this function does not assume that the
      width and height are same.</p>
    <p>Please find suggestions inline.</p>
    Other than that, I could only nitpick some of the styling issues
    given inline.<br>

    For 90 and 270 degree rotation (i.e. rotation_hw) ,

    In my humble opinion, we can use a rectangle content, instead of a
    square content. The function get_muliplane_crc already takes care of
    different width and height.<br>
    Only change will be required in function point_location.<br>
