      <p>
        Test which verifies null filters and filter regions.
      </p>
      <p>
        Four subtests each consist of a small red circle overdrawn with a larger green circle. 
        Filters are applied to three of the red circles, hiding them and showing the green circle.
      </p>
      <p>
        The top left subtest has no filter applied to the circle, so the green circle is visible and the red one is not. 
        The top right subtest applies a filter to the red circle, but there is no corresponding filter element. 
        Thus, a null filter is applied and the red circle is not shown, allowing the green circle to be seen.
      </p>
      <p>
        The bottom left subtest applies an empty filter element with the default filterRegion, and the bottom right 
        subtest applies an empty filter with a non-default filterRegion. In both cases where empty filters are applied, 
        the result of the filter is a transparent black offscreen, thus showing the green circle underneath.
      </p>
