[vtkusers] vtkPlaneSource from a vtkPlaneWidget

[Mike Chinander]

For vtkPlaneSource, you have to set the Origin (you have this commented
out), Point1, and Point2. You shouldn't have to set the PlaneSource's
normal unless you want to change it's orientation as defined by the origin
and the two points.
