The poppler_page_render_to_pixbux api has been removed. The correct way to set
the paper color is to first render to a transparent surface then paint the
surface over the paper color. eg

    surface = cairo_image_surface_create (CAIRO_FORMAT_ARGB32,
                                          IMAGE_DPI*width/72.0,
                                          IMAGE_DPI*height/72.0);
    cr = cairo_create (surface);
    cairo_scale (cr, IMAGE_DPI/72.0, IMAGE_DPI/72.0);
    poppler_page_render (page, cr);
    cairo_set_operator (cr, CAIRO_OPERATOR_DEST_OVER);
    cairo_set_source_rgb (cr, 1, 1, 1);  // Set paper color
    cairo_paint (cr);
