 * 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  2004/03/25 10:29:24  j_novak
 * All LORENE's units are now defined in the namespace Unites (in file unites.h).
 *
 * Revision 1.2  2002/09/06 15:18:52  e_gourgoulhon
 * Changement du nom de la variable "hz" en "hza"
 * pour assurer la compatibilite avec le compilateur xlC_r
 * sur IBM Regatta (le preprocesseur de ce compilateur remplace
 * "hz" par "100").

 *
 * Revision 1.8  2000/02/12  11:18:59  eric
 * Ajout de la version avec determination automatique des bornes de la fenetre
 * graphique.
 *
 * Revision 1.7  2000/02/11  18:44:06  eric
 * Ajout de l'argument draw_bound.
 *
 * Revision 1.6  2000/02/11  16:53:25  eric
 * Utilisation des coordonnees cartesiennes abolues (X,Y,Z) et non plus
