[vtkusers] VTK Screenshot save images different as the visualization in renderer window

[Andrew Maclean]

Use the drop in code in
https://lorensen.github.io/VTKExamples/site/Python/Snippets/, in
particular:
https://lorensen.github.io/VTKExamples/site/Python/Snippets/WriteImage/
These are designed for copy/pasting into your code (there is also a C++
equivalent and a cut-down Java one available too). This code works.

I suspect that you need to set SetInputBufferTypeToRGB()
in vtkWindowToImageFilter.

I'm currently working through all the Python examples and I'll fix this one
when I get to it.


Regards
   Andrew
