[Therion] Distinguishing between survey centrelines and drawings

[Bruce]

The recent kml output discussion reminds me that it took me about three
years of using Therion before I realized that the outputs usually do not
present a consistent or unified set of representations of the cave.  Since
then I have been trying to make sense of it and almost came up with a
tabular representation to improve on the Therion's Features wiki pages, but
then got confused again.

 

This information is already available in the Therion Book and on the wiki in
various places, but I do not recall reading in one place a clear description
or why it is so. Does anyone else get confused by this aspect of Therion's
behaviour?

 

Here is my first cut on an overview description of what goes on and a table
that hopefully clarifies the relationships between 'export' 'selection' and
'file formats'.

Feel free to make suggestions or edit the page to clarify further or to
correct any errors in what I've presented so far.

I've made a few guesses about the capabilities of many of the file formats,
as I'm not familiar with all of them.
