0023200: Visualization - prevent multiple triangulating of a shape that already has been triangulated

Browse Source 
Add new flag IsAutoTriangulated to Prs3d_Drawer. It is True by default.
If this flag is True automatic re-triangulation with deflection-check logic will be applied.
Else this feature will be disable and triangulation is expected to be computed by application itself.

Change the syntax of vdefalts command.
Add new parameter -autoTriang for check of AutoTriangulated functionality.
