        Fix for http://bugzilla.opendarwin.org/show_bug.cgi?id=6002
        WebKit does not properly handle SVG <cursor> element

        Add support for svg cursor images. Also make sure hotspot
        settings are handled correctly. Add tests for handling of css3
        cursor syntax with hotspots in strict and quirks mode. Finally
        implement fallback.
