We already do this with gnuplot/fltk using for example

    ## call the backend print script
    switch (get (opts.figure, "__backend__"))
    case "gnuplot"
      opts = __gnuplot_print__ (opts);
    otherwise
      opts = __fltk_print__ (opts);
    endswitch

Though maybe it should be

    opst = feval (sprintf ("__%s_print__", get_current_backend (), fcn), opts);

(with a suitable definition for get_current_backend) or even
encapsulated in a function like

  opts = __execte_backend_function__ ("print", opts);

?
