function constrainToWorkArea(h_figure)
%constrainToWorkArea Shift figure to fit inside a screen's work area.
%   constrainToWorkArea(h_figure) translates a figure horizontally and
%   vertically if necessary to put the figure inside a screen's work
%   area.  On a PC running Windows, the work area is the region of the
%   screen not obscured by the task bar.  On other systems, the work area
%   is the entire display.
