      FUNCTION IZGNNT(NT)
*.===========>
*.
*.   This function returns in the current picture the Normalisation
*. Transformation stored after NT. This is useful to loop over all
*. the transformations in a picture. If -1 is return the transformation
*. NT has not be found, or the last NT has been found.
*.
*. _Input parameters:
*.
*.  INTEGER NT : Normalisation transformation number .
