I can see 2 different ways of dealing with this API removal. To reuse
as much existing code as possible, you can create
cairo_image_surface_t, let poppler render your page there using
poppler_page_render() and write your own function that will convert
between cairo_image_surface_t and GdkPixbuf.

Another way would involve replacing GtkImage widget with
GtkDrawingArea and drawing your page directly from expose-event/draw
signal handler. Details will depend on whether you'll use GTK+-2 or
GTK+-3.

Cheers,
Tadej
