In an SVG filter chain, this test verifies that the filter region of the
first filter clips the original SourceGraphic. If the test passes, you
should see a green square.

<!--
Use a filter region less wide than the red rectangle SourceGraphic. This
should clip the red rectangle, resulting in a red square.

Offset the red SourceGraphic left. If it wasn't clipped properly, it
will cover up the green square. If it was clipped properly, it won't.
