* $Log: des_domaine.C,v $
* Revision 1.6 2014/10/13 08:53:22 j_novak
* Lorene classes and functions now belong to the namespace Lorene.
*
* Revision 1.5 2014/10/06 15:16:05 j_novak
* Modified #include directives to use c++ syntax.
*
* Revision 1.4 2008/08/19 06:42:00 j_novak
* Minor modifications to avoid warnings with gcc 4.3. Most of them concern
* cast-type operations, and constant strings that must be defined as const char*
*
* Revision 1.3 2005/03/24 14:33:03 e_gourgoulhon
* Ponderation of precis by rhomax-rhomax (to draw domains with
* large r).
*
* Revision 1.2 2004/03/25 10:29:25 j_novak
* All LORENE's units are now defined in the namespace Unites (in file unites.h).
*
* Revision 1.1.1.1 2001/11/20 15:19:29 e_gourgoulhon
* LORENE
*
* Revision 1.4 2001/02/28 09:45:02 eric
* Correction erreur affichage "des_domaine_y" dans des_domaine_z.
*
* Revision 1.3 2000/02/11 16:53:50 eric
* Utilisation des coordonnees cartesiennes abolues (X,Y,Z) et non plus
* des coordonnees relatives (x,y,z).
