[vtkusers] vtkWorldPointPicker does not see vtkImagePlaneWidget (vtk-5.0)

[Boris Avdeev]

Now I am using CellPicker and it works fine. The reason I tried
WorldPointPicker is that it is supposed to be faster and the only
thing I want to get is a world coordinate of a point on a nearest
solid under the cursor. It worked for me in vtk-4.2 regardless of the
documentation, which I do not quite understand anyway (what is "find
the x,y,z world coordinate of a screen x,y,z"?).

Thanks for your help,
Boris
