[Therion] Topodroid import

We just held a weekend of 'intermediate/advanced' digital surveying,
largely about therion usage in the UK.

Expect some questions :-)

One thing that came up was export from topodroid.

It exports directly into therion .th2 format, which is good, but the
exported drawings have a very high point-density on lines. There are
hundreds of small straight line-segments in even quite a short
survey. A large survey is pretty-much unmanageable in xtherion as it
goes so slowly with lots of lines.

It is possible to select each line and use 'edit line' -> 'convert to
curve' to greatly simplify each line, and after doing this things work
much better, but this process is very tedious indeed.

What would it take to be able to select 'all lines' and apply this
transformation in one go, or, even better, could topodroid do this
before export so a much smaller and more useful file is exported?

Any other sugestions for making this less painful?
