[vtkusers] Set plane normal/center of vtkImplicitPlaneWidget manually

[superzz]

Sorry, I meant vtkImplicitPlaneWidget. But misspelt it to
vtkImagePlaneWidget.

Neither SetNormal nor SetOrigin work for vtkImplicitPlaneWidget. No matter
what values I pass to SetNormal and SetOrigin. Its origin is always (0,0,0)
and normal is (0,0,1). But NormalToX/Y/ZAxisOn work. Is it a bug?

Thanks
