I've just had a browse of the patch, and I'm impressed.  Looks like a lot of
work has been put into this.

As the example code shows, the z-up is as trivial as:
  dMatrix3 R;
  dRSetIdentity( R );
  dRFromAxisAndAngle( R, 1, 0, 0, DEGTORAD * 90 );
  dGeomSetRotation( gheight, R );

To make it even easier, we may want provide the rotation directly:
  const dMatrix3* dGetHeightfieldZUpRotation();  

Regardless, I'm definitely looking forward to this being in SVN.

Thanks,
Geoff
