        <p>
          This tests that 'clipPath' elements can be used together and how the clipping paths are intersected.
        </p>
      <p>
        There is a gray-white pattern as a background for the two subtest rectangles. This is to show that the holes that are cut out using clip-paths are transparent.
        The first subtest verifies that when you use the 'clip-path' property on a child element inside a 'clipPath' element the child element is clipped correctly.
        The second subtest verifies that when a 'clipPath' element has a 'clip-path' property the result is the intersection of the two clip paths.
      </p>

      <p>
        The test has passed if the following conditions are met:
			</p>
			<ul>
				<li>There is no red visible.</li>
				<li>No shapes extend outside of the rects that have a thick black border.</li>
				<li>For the left subtest:
					<ul>
						<li>There must be a large blue rect with a transparent smaller rect in it, and the intersection of two circles.</li>
						<li>The borders of the clipregions are shown with black stroke.</li>
						<li>The blue shapes must be visible only inside of these stroked regions.</li>
				 	</ul>
				</li>
				<li>For the right subtest:
					<ul>
						<li>The test on the right must show part of the large blue rect shape with a transparent rect in it, and part of a circle.</li>
						<li>The blue shapes must only be visible inside of the circle that has black stroke.</li>
