Excellent work there David. :)

Any chance you looked into the issue of the extra row of 'invisible' 
samples along the borders of non-wrapped terrains?

While I think the example code should be sufficient, 
dGetHeightfieldZUpRotation may be useful, but perhaps should be 
generalized as addition to the ODE support functions (i.e 
dGetZUpRotation) for other/future applications?

Agreed.
