[vtkusers] pipelines connections

[Jérôme]

The new style connection concerns vtkAlgorithmOutput. In the case of a
comprehensive pipeline (Source -> Filters -> Mappers), this is completely
transparent, whenever you use old or new style.

In the special case where no vtk source is used (meaning vtkAlgorithm with
no input), but a simple raw DataSet construction, there won't be any
"Producer". We cannot use the GetProducerPort( ) for the SetInputConnection(
). If I understand well, using the old SetInput method is still valid?
