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.
There are some group codes (i.e. "62") which are interpreted as
dxfDataType::SHORT. That's right because the dxf-specification defines
"16 bit integer" as the type for the corresponding value.
But readerBase::readGroup() calls readValue(std::ifstream&, unsigned
short). I changed readValue(std::ifstream&, unsigned short) to
readValue(std::ifstream&, short). I found no group code at the dxf-specs
which needs a "16 bit unsigned integer" value. So the
readValue(std::ifstream&, unsigned short) function is obsolete - right?
changes to this plugin that aren't in current CVS yet -- this change is
based on current CVS, not our changed files.)
This changes how shader palette records are parsed to support GLSL per the
OpenFlight 16.1 spec. Existing functionality for 16.0 files is preserved.
The change to Document.h simply adds an enum for VERSION_16_1."
dded GeospatialExtents bounding box class which used doubles
in place of the original usage of osg::BoundingBox.
Added path for computing interpolation elevation data being read from GDAL.
when the binding mode changes, thereby avoiding uncessary calls to dirtyDisplayList.
Note, from Robert Osfield, moved bodies of set*Binding() into Geometry.cpp to avoid
clutter in the header.
