figlower(fignum)
where fignum is the number of the figure to lower. The figure will
be lowerd to the bottom of the GUI stack (meaning that it we be behind other
windows). Note that this function does not cause fignum to
become the current figure, you must use the figure command for that.
Similarly, if fignum is the current figure, it will remain the current
figure (even though the figure is now behind others).
