	* configure.ac:
	* poppler-glib.pc.in:
	* glib/Makefile.am:
	* glib/poppler-page.cc:
	* glib/poppler-page.h:
	* glib/poppler.h:
	* poppler/CairoOutputDev.cc:
	* poppler/CairoOutputDev.h:
	* glib/poppler-features.h.in:
	Make the CairoOutputDev render to a cairo_t instead of a
	cairo_surface_t and expose that functionality in the glib wrapper
	(poppler_page_render).

	* test/Makefile.am:
	* test/gtk-cairo-test.cc:
	Update gtk-cairo-test to use this new interface and add a spin
	button for changing page (#5951).

	* utils/Makefile.am (EXTRA_DIST): Fix warning where this was
	assigned twice.
