This is a neat trick to get around the circularity between GDK, GSK and GTK that we inherit with the GdkPaintable interface. GdkPaintable uses GtkSnapshot GtkSnapshot creates GskRenderNodes GskRenderNodes use GdkTextures GdkTexture will soon implement GdkPaintable This causes a loop that spans GDK, GSK and GTK and this is the easiest way to resolve it without breaking bindings (at least that's the idea).
