        <p>
          This tests that the underlying value of a scale transformation
          is 0.  Since SMIL defines a <em>by animation</em> as being equivalent
          to an additive <em>values animation</em> where the first value is zero and
          the second value is the <em>by</em> value, such an animation would
          begin by post-multiplying a <code>scale(0)</code> transformation to
          the element's underlying transform list.
        </p>
    </d:testDescription>
    <d:operatorScript xmlns="http://www.w3.org/1999/xhtml">
      <p>
        The test consists of two circles: an orange circle on the left,
        which serves as a reference, and a blue circle on the right,
        whose <code>transform</code> attribute is animated.  Animation of
        the circles begins at t=1s and lasts for 3s.
      </p>
      <p>
        The transform animation that applies to the blue circle is of type
        "scale", and specifies <code>by="1"</code>.  Since the animation is
        considered to be equivalent to one that specifies <code>from="0" to="1"</code>,
        when the animation begins the circle will be scaled down to a point,
        and then will be scaled up until it reaches its original size at
        t=4s.
      </p>
    </d:operatorScript>
    <d:passCriteria xmlns="http://www.w3.org/1999/xhtml">
      <p>
        The test is passed if the blue circle on the right is always the same
        size as the orange circle on the left.  The test runs from t=0s until
        t=4s.
