        Fixes: http://bugs.webkit.org/show_bug.cgi?id=11436
        Better SVG integration in WebKit, Part I.

        The patch is mostly about creating a new platform/graphics directory, and
        moving the kcanvas resources (clipper/masker/marker) there (in svg budir),
        with a new name (KCanvasClipper -> SVGResourceClipper). Also fix several ownership
        issues, by using ref counting (the SVG classes now store RefPtrs to the resources).

        KCanvasFilters is still left in kcanvas/ subdirectory, to be converted in a next patch.
        All details of the patch, and upcoming patches can be found in the bug report.
