Option 4 is SVG, but that's on the distant horizon. (It was supposed to be one selling point of xhtml instead of html, but they never got around to developing the xml side.)
I would inform my staff to quit using it immediately but I'd have to go back in time about 5 years to do so. So I'll just inform Jeff Schiller of the news.
