Text scaling

[Keno]

Text doesn't scale with context, but instead is declared via fontsize. It would be fantastic if Compose could automatically figure out the right fontsize. Basically what I wanted to do was draw some text inside a circle, which seems fairly hard to do in the current scheme of things.

Also, what are the actual semantics for hcenter? I was expecting the text to center around the point if I specify (hcenter, vcenter), but that doesn't seem to be the case.

Any progress on this? Is it possible to use relative fontsize now?

The text scaling is too small, which hits the minimum subscript size of MathJax. Producing ugly SVG
