      <p>You should see three rectangles with black stroke. In each of these rectangles there should be
      a series of numbers indicating the value for <a>'seed'</a> that was used on the small rectangle
        directly above the number. The top stroked rectangle should contain 7 smaller rects that all
        have a different filter applied to them, the lower two rectangles should contain 2 smaller rects
        each. The filtered rectangles in each stroked rectangle should all look exactly the same.
        If the filtered rectangles are red, that indicates that the test has failed.
      </p>
      <p>
        The test has passed if:
      </p>
      <ul>
        <li>the top stroked rectangle contains 7 smaller rectangles that are all identical</li>
        <li>the lower left stroked rectangle contains 2 smaller rectangles that are identical</li>
        <li>the lower right stroked rectangle contains 2 smaller rectangles that are identical</li>
        <li>there's no red visible inside the stroked rectangles</li>
