        ---Purpose: Creates an array of polygons,
	-- a polygon can be filled as:
	-- 1) creating a single polygon defined with his vertexs.
	--    i.e:
	--    myArray = Graphic3d_ArrayOfPolygons(7)
	--    myArray->AddVertex(x1,y1,z1) 
	--	....
	--    myArray->AddVertex(x7,y7,z7) 
	-- 2) creating separate polygons defined with a predefined
	--    number of bounds and the number of vertex per bound.
	--    i.e:
	--    myArray = Graphic3d_ArrayOfPolygons(7,2)
	--    myArray->AddBound(4)
	--    myArray->AddVertex(x1,y1,z1) 
	--	....
	--    myArray->AddVertex(x4,y4,z4) 
	--    myArray->AddBound(3)
	--    myArray->AddVertex(x5,y5,z5) 
	--	....
	--    myArray->AddVertex(x7,y7,z7) 
	-- 3) creating a single indexed polygon defined with his vertex
	--    ans edges. 
	--    i.e:
	--    myArray = Graphic3d_ArrayOfPolygons(4,0,6)
	--    myArray->AddVertex(x1,y1,z1) 
	--	....
	--    myArray->AddVertex(x4,y4,z4) 
	--    myArray->AddEdge(1)
	--    myArray->AddEdge(2)
	--    myArray->AddEdge(3)
	--    myArray->AddEdge(1)
	--    myArray->AddEdge(2)
	--    myArray->AddEdge(4)
	-- 4) creating separate polygons defined with a predefined
	--    number of bounds and the number of edges per bound.
	--    i.e:
	--    myArray = Graphic3d_ArrayOfPolygons(6,4,14)
	--    myArray->AddBound(3)
	--    myArray->AddVertex(x1,y1,z1) 
	--    myArray->AddVertex(x2,y2,z2) 
	--    myArray->AddVertex(x3,y3,z3) 
	--    myArray->AddEdge(1)
	--    myArray->AddEdge(2)
	--    myArray->AddEdge(3)
	--    myArray->AddBound(3)
	--    myArray->AddVertex(x4,y4,z4) 
	--    myArray->AddVertex(x5,y5,z5) 
	--    myArray->AddVertex(x6,y6,z6) 
	--    myArray->AddEdge(4)
	--    myArray->AddEdge(5)
	--    myArray->AddEdge(6)
	--    myArray->AddBound(4)
	--    myArray->AddEdge(2)
	--    myArray->AddEdge(3)
	--    myArray->AddEdge(5)
	--    myArray->AddEdge(6)
	--    myArray->AddBound(4)
	--    myArray->AddEdge(1)
	--    myArray->AddEdge(3)
	--    myArray->AddEdge(5)
	--    myArray->AddEdge(4)
	-- <maxVertexs> defined the maximun allowed vertex number in the array.
	-- <maxBounds> defined the maximun allowed bound number in the array.
	-- <maxEdges> defined the maximun allowed edge number in the array.
	--  Warning:
	-- When <hasVNormals> is TRUE , you must use one of
	--	AddVertex(Point,Normal) 
	--  or  AddVertex(Point,Normal,Color)
	--  or  AddVertex(Point,Normal,Texel) methods.
	-- When <hasVColors> is TRUE , you must use one of
	--	AddVertex(Point,Color)
	--  or  AddVertex(Point,Normal,Color) methods.
	-- When <hasTexels> is TRUE , you must use one of
	--	AddVertex(Point,Texel) 
	--  or  AddVertex(Point,Normal,Texel) methods.
	-- When <hasBColors> is TRUE , <maxBounds> must be > 0 and
	--	you must use the
	--	AddBound(number,Color) method.
	-- When <hasEdgeInfos> is TRUE , <maxEdges> must be > 0 and
	--	you must use the
	--	AddEdge(number,visibillity) method.
	--  Warning:
	-- the user is responsible about the orientation of the polygon
	-- depending of the order of the created vertex or edges and this
	-- orientation must be coherent with the vertex normal optionnaly
	-- given at each vertex (See the Orientate() methods).
