// .NAME vtkSISourceProxy
// .SECTION Description
// vtkSISourceProxy is the server-side helper for a vtkSMSourceProxy.
// It adds support to handle various vtkAlgorithm specific Invoke requests
// coming from the client. vtkSISourceProxy also inserts post-processing filters
// for each output port from the vtkAlgorithm. These post-processing filters
// deal with things like parallelizing the data etc.
