[vtkusers] Questions About Python Wrapping

[David Gobbi]

Hi Kyle,

Thanks for sending the files.  I see that the parameters for those methods
are actually smart pointers, and as you have already noted, smart pointers
aren't wrapped.

This has never been an issue in VTK proper or for most VTK projects, since
VTK methods generally use raw pointers.  The header file you sent is closer
to ITK style than to VTK style.

I definitely think that it would be worthwhile to add better smart pointer
handling to the wrappers.

 - David
