[Paraview] Sharing a library I wrote to generate ProgrammableFilters with property panel options

[Miguel Aguirre]

Hello Mr. Shuhao,

Thanks for your contribution. I was facing the XML file creation some days
ago and I also saw the link:

https://blog.kitware.com/easy-customization-of-the-paraview-python-programmable-filter-property-panel/

However, I did not saw your github post in my google search, so maybe a
good idea is to leave a comment in the previous link showing your work. I
think this may increase your visibility, and especially, it will be useful
for Paraview users that are not inscribed in this mailing list.

Best regards,
Miguel Angel AGUIRRE
