[vtkusers] Boolean operation for vtkPolyData

[Marian Panten]

Hi Stefan,

have a look at the TestCollisionDetection1.cxx. You will see the filter can
provide both, the intersection line and the resultion polydata of both
sides. Just test a bit. For example for union operation you use
vtkAppendPolyData to merge the two resultion polydata.
