orient tall with fltk

[Jose]

Hello.

I am trying to use "orient tall" to fill a paper size with a figure as 
explained in
http://octave.1599824.n4.nabble.com/plot-orientation-feature-plot-filling-page-td1635594.html

It seems that orient tall does not work correctly when using fltk in 
octave-3.6.1.

Try

-----
plot([1:10])
graphics_toolkit (1,'gnuplot')
set(gcf,'papersize',[30 20]);
orient tall;
print('-dpdf','foo1.pdf');

graphics_toolkit (1,'fltk')
set(gcf,'papersize',[30 20]);
orient tall;
print('-dpdf','foo2.pdf');
-----

Find attached foo1.pdf (correct one, using gnuplot) and foo2.pdf 
(incorrect, using fltk).

Or am I missing something?
Any workaround?

Jose
