        hit testing does not respect clip paths
        https://bugs.webkit.org/show_bug.cgi?id=15162

        Test: svg/dynamic-updates/SVGClipPath-influences-hitTesting.html
        
        Added a check, if a float point is not only in the shape/object boundaries
        but also is not in the clipped away area of a clipPath.

        Two tests were incorrect, because of the assumption, that clipPath doesn't
        influence hit testing. They needed an update.
        The new test checks, that clipped areas don't throw a hit.
