figure window size with handle graphics

[Jonathan Stickel]

Is there a way to set the figure window size with the new handle 
graphics paradigm?  It used to be as simple as

> __gnuplot_set__ size 0.5

but now those commands seem to be completely ignored if octave plotting 
commands are used.  I really find setting the window size to be helpful 
in producing publication quality plots.

Thanks,
Jonathan
