email comments from Andew Sampson,
"I've contacted Terrex, and obtained the 2.2 version
of their trpage library. The library included a
fork of OSG 0.9.8's txp plugin, modified to load 2.1+
txp DBs.
I've done the work of incorporating the changes made
to OSG's txp plugin since 0.9.8 into Terrex's fork.
The forked version is now up-to-date with the changes
made to OSG 0.9.9 and 1.0.
Terrex made a lot of changes (especially differences
in whitespace), so the diff between the forked version
and OSG 1.0's txp plugin is yucky. I did my best, but
keep in mind that this is the result of a 4-way merge
(kinda... terrex-0.9.8, stock-0.9.8, stock-0.9.9,
stock-1.0).
I really want to see this forked version merged back
into the main OSG branch. The new features offered by
this version of the plugin (2.1+ support, variable
LOD support, bug fixes) are worth the trouble."

Don Tidrow then took this code and added his work.

Robert Osfield then fixed all the warnings that abound in the trpage code base.
get positioned correctly when the TXP database was built using the
'tile-offset' mode. I've included a tarball with what I believe are the
needed changes - they work for the sample databases I have available,
but not all conditions have been tested. I've set things up such that
these changes shouldn't affect 'normal' txp databases."
