% plotSalientLocation - plots the attended location into an existing figure.
%
% plotSalientLocation(winner,lastWinner,salParams,shapeData)
%    Plots the winning location into the current figure. 
%    Depending on the settings in salParams, the contour of the 
%    attended region or a circle centered at the attended location 
%    is drawn in yellow. If there is a valid lastWinner, 
%    a red line connects lastWinner with winner.
%       winner: the attended location in image coordinates.
%       lastWinner: the previously attended location (-1 for none).
%       salParams: structure with saliency parameters.
%       shapeData: structure array with information on the attended 
%          region from estimateShape.
%
% plotSalientLocation(winner,lastWinner,salParams)
%    If no shapeData are passed, a circle is drawn at the attended
%    location.
