Moved FontSetup and two helper classes from render.pdf to fonts package.

FontSetup has the PDF fonts as the default, but this class can be extended
if/when another renderer needs its own font setups.  (Cannot do this, however,
for AWT's FontSetup at the moment, because its setup() has a different
signature.)
