     Saves pixbuf in format 'type' by feeding the produced data to a 
     callback. Can be used when you want to store the image to
     something  other than a file, such as an in-memory buffer or a
     socket.   If 'error' is set, 'FALSE' will be returned. Possible
     errors include those in the 'GDK_PIXBUF_ERROR' domain and whatever
     the save function generates.
