      <p>
        Verify the basic operation of the different lights used in the feDiffuseLighting
        and feSpecularLighting elements. The test uses the same feDiffuseLighting filter,
        using different lights.
      </p>
      <p>
        The first row shows different settings for feDistantLight. The second row shows
        different settings for fePointLight. The last row shows different settings for
        feSpotLight.
      </p>
    </d:testDescription>
    <d:operatorScript xmlns="http://www.w3.org/1999/xhtml">
      <p>
        Run the test. No interaction required.

      <p>
        The rendered image should look approximately like the reference image, except for the last
        feSpotLight test for which a reference image could not be created. The reference image may not be pixel accurate. However, the rendered image should show
        at least 'similar' lighting results and bump maps.
