     HISTORIQUE DES MODIFICATIONS   :
     --------------------------------

      14-05-98 : GG ; Disable using MFT when the symbol
			CSF_MDTVFontDirectory is not defined.
		      See dirMFTisDefined changes. 

      30-01-98 : GG ; SPEC_MFT
              L'utilisation des polices MFT devient parametrable.
	      Le driver doit utiliser la methode UseMFT() pour
	      savoir s'il doit utiliser ou non les polices
	      MDTV a la place des polices system.

		-> Modifications dans SetFontMap()
		-> Nouvelle methode UseMFT()
