I forgot the 3rd technique:

 - make the renderer interface pluggable. That means you
   have two modules - the one that decides what to print,
   and the one that converts these decisions to PDF.
   The pluggable renderer could behave like a GDI
   device context. Then build a Mock Renderer who
   can test that the correct print decisions were made.
   This technique cannot test the PDF module itself,
   yet it can test the part that ought to change more often.

That technique is a form of "Mock Graphics". Google for that, because
JUnit has literature on it.
