/**
 * The {@code Stroke} 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}.
 * Stroking a {@code Shape} 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}.
 * <p>
 * The methods of the {@code Graphics2D} interface that use the
 * outline {@code Shape} returned by a {@code Stroke} object
 * include {@code draw} and any other methods that are
 * implemented in terms of that method, such as
 * {@code drawLine}, {@code drawRect},
 * {@code drawRoundRect}, {@code drawOval},
 * {@code drawArc}, {@code drawPolyline},
 * and {@code drawPolygon}.
 * <p>
 * The objects of the classes implementing {@code Stroke}
 * must be read-only because {@code Graphics2D} does not
 * clone these objects either when they are set as an attribute
 * with the {@code setStroke} method or when the
 * {@code Graphics2D} object is itself cloned.
 * If a {@code Stroke} object is modified after it is set in
 * the {@code Graphics2D} context then the behavior
 * of subsequent rendering would be undefined.
