Seems like these are more likely associated with the surface and not the
drawing state.

I see something like:

surface = cairo_ps_surface_create ();

while (more pages)
{
	set page options (surface);
	draw_surface (surface);
	cr = cairo_create (surface);
	cairo_show_page (cr);
	cairo_destroy (cr);
}

In this way, draw_surface is independent of the target, and only this
outer loop "knows" about printing at all.
