[vtkusers] vtkPointPicker2D

[K.R.Subramanian]

I was trying to use this picker as I was operating on 2D images. But it consistently
returns a point id of -1, when asked to determine the closest point..

I switched to vtkPointPicker and it works fine(of course zeroing out the z coordinate).
I  am missing something here.. the 2D version should be more efficient..

Thanks.
