Return the direction corresponding to a (X,Y) translation.

Parameters:
aDx X translation
aDy Y translation
Warning:
The translation must be defined according to one of the 8 Freeman directions, precisely, that is to say, if aDx and aDy are both different from 0, |aDx| must be equal to |aDy|. Otherwise, the correctness of the the result is not guaranteed.
Exceptions:
