[vtkusers] Delaunay2D problems

[Mathieu Malaterre]

David,

	This is just a design, VTK is command driven. You can set a pipeline 
and never call Update so nothing won't happen. This is great for two 
different pipelines, depending on user input. You update the first one 
or the second, and you don't waste time on the one not used.

Does it make sense ?
