Kristian contributed a poppler-based pdf2png script which we use in
the cairo test suite. You can see it here:

http://cvs.cairographics.org/cairo/test/pdf2png.c?rev=1.1&view=markup

That version hides cairo more than I'd like. It would be a lot more
interesting if poppler had an interface to just render a PDF file to a
cairo_surface_t.

Oh, and I guess that's the problem you have in question #1. The
version above does require using poppler with GDK.

Kristian has mentioned interest in having the more direct cairo
integration in poppler. And I suspect it wouldn't really require much
new code in poppler---just a means for exporting the desired
interface.

If poppler did have more direct cairo integration, the answer to your
second question is that you would then just need to call:

	cairo_surface_write_to_png
