// Declare a Chart Framework "cf_3DPolygon" class.
//
// Class cf_3DPolygon is virtually identical to class 
// cf_3DPolyLine -- it abstracts a set of graphable 3D-Points, 
// along with other polygon attributes, and is used the base
// class capabilities of the cf_3DPointSeries object.
//
// The main differences lie in how a polygon gets rendered in 2D/3D
// mode, versus how the base polyline class gets rendered.  Thus,
// we will over-ride some of the base class functionality.
//
// Additionally, since cf_3DPolygons are the often-used components 
// of pictChart objects, they will use a lot of HSE (Hidden Surface 
// Elimination) and DSORT (Depth Sorting) functionality.
