Python IDE autocompletion for upcoming VTK 9.1

I’ve been crazy busy and haven’t followed what’s going on with Python, sorry about that.

This morning I did a clean master pull / VTK build to test a new filter. I found that the way I’ve been testing/debugging Python test scripts for the last many years no longer works. For example:

~/Develop/Bisect/debug/bin/vtkpython TestExtractPoints.py

Gives me a bunch of import errors. As a member of the uninformed, unwashed masses, let me ask: what do I need to do to get this working again?
