[librsvg] Test pservers-pattern-09-f.svg from the official test suite

    Test pservers-pattern-09-f.svg from the official test suite
    
    I believe the official reference image is wrong.  The test SVG says that
    both cases in the file should render the fallback color (green), and
    that is indeed what we do.  However, the official reference image only
    renders the first case in green, and doesn't render the second case at
    all.

+      <p>
+        Test that an invalid xlink:href on a 'pattern' element has no effect on the pattern, and that the
+        pattern isn't rendered since the default 'width' and 'height' is 0.
+        A subtest that explicitly specifies 'width' and 'height' as 0 is added as a reference. 
+        Both of these cases should result in the fallback color being used.
