NAME

       Geometry::Primitive::Polygon - Closed shape with an arbitrary number of points.

DESCRIPTION

       Geometry::Primitive::Polygon represents a two dimensional figure bounded by a series of points that represent a closed path.

SYNOPSIS

	 use Geometry::Primitive::Polygon;

	 my $poly = Geometry::Primitive::Polygon->new;
	 $poly->add_point($point1);
	 $poly->add_point($point2);
	 $poly->add_point($point3);
	 # No need to close the path, it's handled automatically
