/**
* 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.registerShape('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>.
