[Therion] Okular pdf viewer

[Stu Walker]

I have used the TexWorks PDF viewer that comes with MikTeX on Windows in
the past

I am not sure if it is better than Okular, but found it useful for building
up cave surveys with the PDF still open and updating

(it is built for when you are writing LaTeX documents and your PDF file is
being updated regularly, each time you hit recompile in LaTeX)
