[vtkusers] scale vtkPlaneWidget

[Anka Kochanowska]

But, instead of scaling, you could use
planeWidget->PlaceWidget(xmin, xmax, ymin, ymax, zmin, zmax)
It will not make prop3d, but should do what you intend. (Using for instance
min -0.1, max +0.1)

Setting prop 3d is an option but, would be a little artificial.
