setting position of fltk figure windows

[John W. Eaton]

Using the current development sources, neither of the following
functions are setting the position of the figure window.  Can anyone
else duplicate this behavior?

  function f ()
    figure ("position", [200, 400, 400, 50]);
    drawnow ();
  endfunction

  function g ()
    h = figure ();
    set (h, "position", [200, 400, 400, 50]);
    drawnow ();
  endfunction

  graphics_toolkit fltk
  f ()
  g ()

However, executing the following at the command line does work:

  h = figure ();
  set (h, "position", [200, 400, 400, 50]);

provided that the figure is drawn before the set command is executed.
So neither of the following are working for me either:

  h = figure (); set (h, "position", [200, 400, 400, 50]);

  figure ("position", [200, 400, 400, 50]);

Ah, OK, the following does work (well, apparently only sometimes; or
maybe only for the first plot window after setting the graphics
toolkit to fltk):

  function g ()
    h = figure ();
    drawnow ();
    set (h, "position", [200, 400, 400, 50]);
  endfunction

But even if this way did work reliably, it makes a larger window flash
on the screen before it is resized and moved.  And in any case,
shouldn't any of these work?  And shouldn't I be able to set the size
of the window before it is drawn?

To confuse things even more, gnuplot behaves differently, of course.
