vtkAssemblys visiblity is ignored if it is added to another assembly
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
If you have two vtkAssembly where one is added to the other one and the added assembly contains e.g. an vtkActor the visiblity of this added assembly is ignored. Instead, the visibility of the vtkActor is only set by its visibility flag and the toppest assembly visibility flag.
The attached code shows the problem: The actor line2 should not be visible, since its assembly line2Assembly is set to invisible, but it is visible!
