-25-02-98 : FMN ; PERF.27: Optimisation of view creation from existing view
-11-03-98 : STT ; S3558
-19-03-98 : FMN ; Probleme dans FitAll car la methode WNT_Window::Size(Real,Real)
-ne marche pas.
-08-04-98 : STT ; suppr. S3558
-10-04-98 : CAL ; Ajout des methodes RefToPix et PixToRef
-13-06-98 : FMN ; Probleme dans FitAll car la methode WNT_Window::Size(Real,Real)
-ne marche pas. Contournement en appelant WNT_Window::Size(Int,Int).
-16-08-98 : CAL ; S3892. Ajout grilles 3d.
-09-09-98 : CAL ; S3892. Generalisation de TrsPoint.
-06-10-98 : CAL ; Ajout d'un TIMER si CSF_GraphicTimer est definie.
-16-10-98 : CAL ; Retrait d'un TIMER si CSF_GraphicTimer est definie.
-06-11-98 : CAL ; PRO ?????. Probleme dans ZFitAll si un point dans la vue.
-29-OCT-98 : DCB : Adding ScreenCopy () method.
-REMARQUES :
------------
-About FitAll() multiple. This probleme is caused by missing
-precision of transformation matrices. If it is supposed that
-projection is made in the plane (U,V), there is a difference
-after several Zoom - compared to the exact value (cf ZoomX).
-Don't forget that the matrices work in float and not in double.
-To solve the problem (for lack of a better solution) I make 2 passes.
