/**
 * The {@code PathIterator} interface provides the mechanism
 * for objects that implement the {@link java.awt.Shape Shape}
 * interface to return the geometry of their boundary by allowing
 * a caller to retrieve the path of that boundary a segment at a
 * time.  This interface allows these objects to retrieve the path of
 * their boundary a segment at a time by using 1st through 3rd order
 * Bézier curves, which are lines and quadratic or cubic
 * Bézier splines.
 * <p>
 * Multiple subpaths can be expressed by using a "MOVETO" segment to
 * create a discontinuity in the geometry to move from the end of
 * one subpath to the beginning of the next.
 * <p>
 * Each subpath can be closed manually by ending the last segment in
 * the subpath on the same coordinate as the beginning "MOVETO" segment
 * for that subpath or by using a "CLOSE" segment to append a line
 * segment from the last point back to the first.
 * Be aware that manually closing an outline as opposed to using a
 * "CLOSE" segment to close the path might result in different line
 * style decorations being used at the end points of the subpath.
 * For example, the {@link java.awt.BasicStroke BasicStroke} object
 * uses a line "JOIN" decoration to connect the first and last points
 * if a "CLOSE" segment is encountered, whereas simply ending the path
 * on the same coordinate as the beginning coordinate results in line
 * "CAP" decorations being used at the ends.
