[vtkusers] Removing vtkLineWidget "end point balls"

[Karnowski, Thomas Paul]

Hello, I have an application where I'm using vtkLineWidgets to mark
various things.  When you select the widget its endpoints turn into
"balls".  Does anyone know how to disable this or control its
properties?  I've looked through the GetLineProperty values and I don't
see anything.
