        <rdar://problem/4713280> Would like to get an array of bounding rects rather than just the union of them for a DOMRange
        <rdar://problem/4804317> Would like SPI to get bounding box for a DOM range without having to change the selection

        Added lineBoxRects and boundingBox to Range and DOMRange. These methods correspond to the DOMNode methods.

        (WebCore::kit):
        (-[DOMNode lineBoxRects]):
        (-[DOMRange boundingBox]):
