kgv 3483c64453 0032247: VIS, IVtkOCC_ShapeMesher - allow disabling auto-triangulation behavior
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.
