Again lots of variety here. @mwahl, others is it worth splitting up?

@spicyj I modified the graphie `label()` so if you don't want latex, instead of getting Raphael's text, you get a span positioned in the same way as we do for latex, but without the code tag. Raphael text looked wrong and I'm not sure we use it anywhere, but let me know if you think this is a bad idea for some reason.
