[vtkusers] "manually" specify extents for vtkXMLPRectilinearGridWriter

[Andy Bauer]

You'll probably need to set the vtkInformation for the whole extent and the
extent translator in your pipeline. The easiest way to do this may be by
using a vtkTrivialProducer or the vtkPVTrivialProducer in Paraview.
