[vtkusers] [vtk-developers] can a programmable source be made "time aware"

[Berk Geveci]

I am writing this without looking at the code. I suspect that one will have
to add support for RequestInformation and RequestUpdateData to the
programmable filter to support time. That's what we had to do in the python
programmable filter we use with ParaView.
