/**
 * Class: mxActor
 *
 * Extends <mxShape> to implement an actor shape. If a custom shape with one
 * filled area is needed, then this shape's <redrawPath> should be overridden.
 * 
 * Example:
 * 
 * (code)
 * function SampleShape() { }
 * 
 * SampleShape.prototype = new mxActor();
 * SampleShape.prototype.constructor = vsAseShape;
 * 
 * mxCellRenderer.prototype.defaultShapes['sample'] = SampleShape;
 * SampleShape.prototype.redrawPath = function(path, x, y, w, h)
 * {
 *   path.moveTo(0, 0);
 *   path.lineTo(w, h);
 *   // ...
 *   path.close();
 * }
 * (end)
 * 
 * This shape is registered under <mxConstants.SHAPE_ACTOR> in
 * <mxCellRenderer>.
 * 
 * Constructor: mxActor
 *
 * Constructs a new actor shape.
 * 
 * Parameters:
 * 
 * bounds - <mxRectangle> that defines the bounds. This is stored in
 * <mxShape.bounds>.
 * fill - String that defines the fill color. This is stored in <fill>.
 * stroke - String that defines the stroke color. This is stored in <stroke>.
 * strokewidth - Optional integer that defines the stroke width. Default is
 * 1. This is stored in <strokewidth>.
