I don't think this code would be the best solution as all the
hint commands from the CharStrings dictionary will be lost.
It would be better if freetype made the raw font data available.

The code would be useful for printing truetype fonts to printers
that don't support Type 42. It could also be used for printing
any other scalable font type supported by freetype.
