<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.
