function sbresize(create_flag,fig)
%SBRESIZE Resize function for Signal Browser.
%   SBRESIZE will resize only those objects which need resizing.
%   SBRESIZE(1) will resize every object.  Use this syntax at creation
%   of the figure.
%
%   SBRESIZE(create_flag,fig) resizes the browser with figure handle fig.
