        Test compositing of animated fill opacity.

    </d:testDescription>
    <d:operatorScript xmlns="http://www.w3.org/1999/xhtml">
      <p>
        First click once on "fade in" and
        then, once the animation has completed, click once on "fade out". 
        </p>
    </d:operatorScript>
    <d:passCriteria xmlns="http://www.w3.org/1999/xhtml">
      <p>The first time you
        select the link 'fade in', you should see a green square appearing,
        gradually and smoothly fading from zero to 100% opacity over the
        course of three seconds. This square is in front of and thus
        obscures the lower left circle, but is behind the upper right
        circle which is thus composited on top of the animated green
        square. Then, when you click on "fade out", the green square will
        gradually disappear, smoothly fading from 100% to zero opacity
        over the course of three seconds.
        </p>
        <p>
        The rendered picture should match the reference image, (except
        for possible variations in the labelling text (per CSS2 rules))
        after activating the link on the fade-in button the first time
        and waiting three seconds for the animation to complete. The picture
        should remain looking the same way indefinitely, until another
        link is activated.
      </p>
      	<!--
        With a second click on "fade in", however, the behavior might
        be different. In the case of having a first click on "fade in",
        waiting three seconds, and then immediately perform a first click
        on "fade out", waiting three seconds, and then immediately perform
        a second click on "fade in", you should see the following. After
        the first click on "fade in", the red square goes from zero to 100%
        opacity. After the first click on "fade out", the red square goes
        from 100% to zero opacity. After the second click on "fade in",
        however, the red square goes from zero to 100% opacity, and then
        goes back from 100% to zero opacity. This is because of the
        hyperlinking rules as they relate to resolved start times in the
        SMIL Animation specification.
