Hm, I simply searched Tux_AQFH for sgHPRfromVec3.
There is one occurence in hooks.cxx, but only hpr[0]
is used, so this one is uninteresting.
There is also one in whale.cxx:

  sgHPRfromVec3 ( heading, to_tux ) ;
[... much deleted]
	coord.hpr[1] = blend_angle ( coord.hpr[1], -heading[1] ) ;

Look at the minus-sign!

Bye bye,
