  40  * This class abstracts a number of features for which the Java 2D
  41  * implementation relies on proprietary licensed software libraries.
  42  * Access to those features is now achieved by retrieving the singleton
  43  * instance of this class and calling the appropriate methods on it.
  44  * The 3 primary features abstracted here include:
  45  * <dl>
  46  * <dt>Shape createStrokedShape(Shape, [BasicStroke attributes]);
  47  * <dd>This method implements the functionality of the method of the
  48  * same name on the {@link BasicStroke} class.
  49  * <dt>void strokeTo(Shape, [rendering parameters], PathConsumer2D);
  50  * <dd>This method performs widening of the source path on the fly
  51  * and sends the results to the given {@link PathConsumer2D} object.
  52  * This procedure avoids having to create an intermediate Shape
  53  * object to hold the results of the {@code createStrokedShape} method.
