0027655: Visualization - AIS_Triangulation disappears after setting non-zero transparency

Browse Source 
Add a new methods in AIS_Triangulation: SetTransparency, UnsetTransparency, HasVertexColor, updatePresentation.
Add a new methods in Graphic3d_ArrayOfPrimitives: AddVertex(gp_Pnt, Graphic3d_Vec4ub) and SetVertexColor(Standard_Integer, Graphic3d_Vec4ub).
Type of color of array in AIS_Triangulation is Graphic3d_Vec4ub now.
