I don't think it works ... 

-       cairo_set_alpha (cr, opaque ? 1 : 0.8);
+       cairo_set_source_rgba (cr, 1, 1, 1, opaque ? 1 : 0.8);
 
        cairo_show_surface (cr, temp_surface, width, height);

needs to use some not-yet-landed (but soon to land): 

        cairo_set_source_surface (cr, temp_surface, 0, 0);
        cairo_paint_with_alpha (cr,  opaque ? 1 : 0.8);
