/**

 * The <code>Stroke</code> interface allows a

 * {@link Graphics2D} object to obtain a {@link Shape} that is the

 * decorated outline, or stylistic representation of the outline,

 * of the specified <code>Shape</code>.

 * Stroking a <code>Shape</code> is like tracing its outline with a

 * marking pen of the appropriate size and shape.

 * The area where the pen would place ink is the area enclosed by the

 * outline <code>Shape</code>.

 * <p>

 * The methods of the <code>Graphics2D</code> interface that use the

 * outline <code>Shape</code> returned by a <code>Stroke</code> object

 * include <code>draw</code> and any other methods that are

 * implemented in terms of that method, such as

 * <code>drawLine</code>, <code>drawRect</code>,

 * <code>drawRoundRect</code>, <code>drawOval</code>,

 * <code>drawArc</code>, <code>drawPolyline</code>,

 * and <code>drawPolygon</code>.

 * <p>

 * The objects of the classes implementing <code>Stroke</code>

 * must be read-only because <code>Graphics2D</code> does not

 * clone these objects either when they are set as an attribute

 * with the <code>setStroke</code> method or when the

 * <code>Graphics2D</code> object is itself cloned.

 * If a <code>Stroke</code> object is modified after it is set in

 * the <code>Graphics2D</code> context then the behavior

 * of subsequent rendering would be undefined.
