There are two classes for polygonal lines in JavaView. PgPolygon contains
a single polygonal line implicitly determined by a sequence of vertices.
PgPolygonSet contains a number of polygonal lines and a set of vertices.
Each line is determines by the list of indices of their vertices. This
applet shows a sample instance of PgPolygonSet.
