function theResult = control(self, theStyle, ...
						theNormalizedPosition, thePixelOffset, ...
						varargin)

% ps/control -- Create UIControl for "ps".
%  control(self, 'theStyle', theNormalizedPosition, thePixelOffset)
%   creates the given control and enables it to be repositioned
%   in normalized and pixel coordinates during resizing.  The
%   style may be given as a string, or as an actual control
%   already present in the figure associated with self, a "px"
%   object.  Additional name/value pairs can be appended to the
%   argument list to change the properties of the control.
%
%   Note: scrollbars along the edge of the figure can be specified
%   by their location: 'bottom', 'right', 'top', or 'left'.  The
%   "String" property will be set to one of those.  For other
%   controls, the "String" can be set with a name/value pair.
