      <p>
        Tests the default behaviour of feComponentTransfer
      </p>
      <p>
        The test displays two rects with the same gradient fill. The gradient
        fill has the stops red, green, blue and black all of which are evenly
        spaced.
      </p>
      <p>
        The first rect with the 'Reference' label beneath it has an
        feComponentTransfer filter applied to it. This filter specifies a
        'linear' transform for the Red component such that Red is transformed to
        Black. The Green component is specified as an 'identity' transform. The
        remaining components (Green, Alpha) are unspecified and by default
        must be treated as 'identity' transforms.
      </p>
      <p>
        The second rect with the 'Default' label beneath it has an
        feComponentTransfer filter applied to it. This filter specifies a
        multiple transforms from the Red component. The last transform
        specified for the Red component is a 'linear' transform that shifts Red
        to Black. This is the transform that should be used by a conforming
        implementation. There are no other components specified for the filter
        of the second rect. A conforming implementation should treat
        unspecified components in an feComponentTransfer as 'identity'.
