So, if anyone out there has experience of mapping from WTK to OSG, specifically
in regards to what should happen to rotation angles, and quarternians, I would
be most grateful - and perhaps my wall could then be repainted beige instead of

I don't know about OSG to WTK specifically, but I might have a suggestion.
When translating an orientation (or more specifically, a rotation) from
one coordinate system to another, the correct procedure is to first
convert from your target coordinate system to your original coordinate
system, then apply the rotation, then convert back. So
-1
R' = M * R * M
Where R' is the desired rotation in OSG coordinates, R is the rotation
in WTK coordinates, and M is the conversion matrix (or quat) from WTK
coordinates to OSG coordinates.
Now, usually when I explain this, I get the ordering wrong, so if it
doesn't work first try, just try reversing the order :-)
Hope this helps!
