        SVG selection text foreground colour does not respect user settings
        https://bugs.webkit.org/show_bug.cgi?id=15997

        Add two subphases SVGTextPaintSubphaseGlyphFillSelection and
        SVGTextPaintSubphaseGlyphStrokeSelection for painting selected
        text on SVG. Selected texts are painted with style from
        getCachedPseudoStyle() instead of style().
