IVtkOCC_Shape now stores Prs3d_Drawer object used by IVtkOCC_ShapeMesher and IVtkOCC_SelectableObject. IVtkOCC_ShapeMesher::internalBuild() made more consistent to AIS_Shape::Compute() in cleaning/triangulating shape. Added command ivtkdefaults similar to vdefaults managing triangulation default parameters.
