      <p>
        This tests feDisplacementMap without feImage. The input geometry is also used as the displacement map.
      </p>
      <p>
        The bottom subtest tests that not specifying the 'xChannelSelector' attribute has the same effect as if 'A' was specified.
      </p>
      <p>
        In both cases the filter input image consists of a gradient that is rendered using the default 'color-interpolation' which is 'sRGB'.
        The default colorspace for filter primitives is 'linearRGB'. The filtering operation happens in 'linearRGB' space and the
        result is then transformed back to 'sRGB' space for display.
      </p>

        The test has passed if:
      </p>
      <ul>
        <li>the top rectangle is overlapped by a gradient that has its blackest part centered around the vertical green line that splits the top rectangle</li>
        <li>the bottom right corner of the area covered by the top gradient is aligned with the corner just below the top rectangle</li>
        <li>the bottom rectangle is overlapped by a gradient that is displaced upwards with the maximum displacement the middle indicated by the vertical green line that splits the bottom rectangle</li>
        <li>no part of the bottom gradient extends outside the bottom rectangle</li>
        <li>both gradients use the same gradientcolors</li>
