[racket] [scribble] rendering of fractions

I've pushed an update to number-snip% so that it subscribes to the
'png-bytes and 'text parts of the file/convertible protocol.

I think that all you'd need to do now is to use pretty-print to print
and set some hooks so that when you see a rational number, you create
a number-snip% instead. That is, you should not need to deal with
simple-settings and all that nonsense.
