[vtkusers] picking from resliced output

[Rafael]

Hi
I have the same question and it works fine for me.

vtkCellPicker* picker = vtkCellPicker::New();
        picker->SetTolerance(0.005);
vtkImagePlaneWidget* planeWidgetX = vtkImagePlaneWidget::New();
        planeWidgetX->SetPicker(picker);
        ...
