0030854: Visualization, AIS_ViewCube - pack triangulations into common array(s)

Browse Source 
Presentation computation has been modified to merge triangulations per box part type.
Prs3d_Drawer::FaceBoundaryDraw() flag is now handled for drawing box sides edges.

Graphic3d_ArrayOfPrimitives has been extended by auxiliary methods:
- ::AddSegmentEdges(), ::AddTriangleEdges(), ::AddQuadEdges() raising exception on wrong primitive type.
- ::AddQuadTriangleEdges() splitting quad into indexed triangulation;
- ::AddTriangleStripEdges() splitting triangle strip into indexed triangulation;
- ::AddTriangleFanEdges() splitting triangle fan into indexed triangulation;
- ::AddPolylineEdges() splitting polyline into indexed segments.
