Good monday pfMorning,

a solution has been found. Not using quaternions (the makeVecRotVec function
behaves like the pfMatrix one).
For those who are interested in solving that king of GIMBLE-LOCK problem, eMail
me, Ill give you a detailed answer.

In fact the solution uses hard coded matrix from geometric determinist operations
(vector products) that are safe.

Thanks for your answers,
    Marc.
