This file should be used by G4 developers and category coordinators
to briefly summarize all major modifications introduced in the code
and keep track of all category-tags.
It DOES NOT substitute the  CVS log-message one should put at every
committal in the CVS repository !

14th January 2003  John Allison  (openinventor-V05-00-00)
- Removed vertex.transform (*fpObjectTransformation) from
  G4OpenInventorSceneHandler::AddPrimitive (const G4Polyhedron& polyhedron).
  Symptom was that polyhedron objects were being transformed twice.
  The transformation is stored in 
  G4OpenInventorSceneHandler::PreAddThis
  ...
  G4OpenInventorTransform3D oiTran (objectTransformation);
  SoSFMatrix* oiMat = oiTran.GetOIMatrix();
  SoMatrixTransform* xform = new SoMatrixTransform;
  xform->matrix.setValue(oiMat->getValue());
  currentSeparator->addChild(new SoResetTransform);
  currentSeparator->addChild(xform);
}

27th November 2002  John Allison  (vis-V04-01-08)
- Improved algorithm of CompareForKernelVisit.

14th August 2001  John Allison  (vis-V03-02-11)
- Improved KernelVisitDecision - but see note therein.
