        - fixed "SVGTextElement.getNumberOfChars is broken for altGlyph (affects Acid3 test 79)"
        http://bugs.webkit.org/show_bug.cgi?id=17062

        * svg/SVGAltGlyphElement.cpp: Added. Implementation for new element.
        (WebCore::SVGAltGlyphElement::SVGAltGlyphElement):
        (WebCore::SVGAltGlyphElement::~SVGAltGlyphElement):
        (WebCore::SVGAltGlyphElement::setGlyphRef):

        (WebCore::SVGAltGlyphElement::format):
        (WebCore::SVGAltGlyphElement::childShouldCreateRenderer):
        (WebCore::SVGAltGlyphElement::createRenderer): For now, this just renders as a tspan,
        which is right for everything besides the alternate glyph substitution itself.
