This new private API, _gtk_style_context_is_background_opaque(), is meant to be used by internal Gtk+ wigets to optimize fast paths for cases where applicable. One such use would be to use a CAIRO_CONTENT_COLOR surface instead of CAIRO_CONTENT_COLOR_ALPHA. https://bugzilla.gnome.org/show_bug.cgi?id=754658
