	Definition of the five graphical primtives
	* Line
	* Arc
	* Polygon
	* Circle
	* Text

	Unless a need is found -
	Graphical primtives should not have user defined attributes.

	Those attributes should be delagated to groups in order to
	promote support for amking behaviors apply to any custom shape
	as opposed limiting it to a single primitve.
