We were already using the XML parser for SVG files when opening at the top level. This patch makes things consistent by using the same code path when parsing SVG-as-image. We also make some tweaks in SVG presentation attribute handling since we can no longer rely on the HTML length attribute parsing quirk when parsing width/height attributes.
