Hey Ben, congratulations :-) (for the twins, not the load of work)

I had a look at the gl2ps examples and they call glFlush() (force
execution of GL commands in finite time) at the end of their drawing
operations. I think could be a reason that not all primitives were drawn
when we call print and Fl::check twice gives enough time.

Could you please add glFlush() in gl2ps-renderer.cc after
opengl_renderer::draw (go);?

I can also provide a complete diff the next days with this and some
debugging outputs if this is more comfortable for you.
