        Fix for http://bugs.webkit.org/show_bug.cgi?id=11461 HitTestResult
        should be split into HitTestRequest and HitTestResult

        This patch creates a new struct called HitTestRequest that holds
        the three boolean values (readonly, active, and mouseMove) that
        were formerly a part of HitTestRequest. all hitTest() and
        nodeAtPoint() functions now take a HitTestRequest in addition to
        the HitTestResult.

        show_bug.cgi?id=11461 HitTestResult should be split into
        HitTestRequest and HitTestResult

        (-[WebHTMLView elementAtPoint:allowShadowContent:]): The
        HitTestResult initializer now just takes a point.
