[racket] improving image quality

I think it would make sense for plot to allow picts as valid #:label
arguments and hopefully not too much of a pain to add. (If it is painful
for some reason, I'm happy to help.) Then you'd have to make up your own
pict.

Oh! Or in this case you could use unicode:

  y = x²
