        Fix for <rdar://problem/5616052> SVGs with width or height of 100%
        hang when used as a background-image (16164)

        * platform/graphics/svg/SVGImage.cpp:
        (WebCore::SVGImage::size): Use valueAsPercentage() for percents
        instead of valueInSpecifiedUnits(). valueInSpecifiedUnits()
        returns, for example, 50 for 50%, so multiplying percentages by the
        default size of 300 x 150 led to ridiculously huge dimensions for
        SVG images, and the subsequent hang.
