-HISTORIQUE DES MODIFICATIONS :
---------------------------------
-00-09-92 : GG ; Creation.
-02-10-96 : FMN ; Suppression appel Redraw sans MustBeResized()
-05-06-97 : FMN ; Correction FitAll()
-30-06-97 : GG ; Correction + Optimisation de Panning(...)
-On fait la translation + le zoom en une seule
-operation au lieu de 2 precedemment qui etait buggee.
-09-07-97 : FMN ; Correction FitAll() sur le Ratio
-16-07-97 : FMN ; Correction FitAll() sur le calcul de la Box
-22-07-97 : FMN ; Ajout mode RetainMode pour le Transient
-15-12-97 : FMN ; Ajout texture mapping
-17-12-97 : FMN ; CTS19129 Correction FitAll() multiple
-18-12-97 : FMN ; Ajout mode Ajout
-24-12-97 : FMN ; Remplacement de math par MathGra
-24-12-97 : CQO ; BUC50037 Xw_Window -> Aspect_Window
-31-12-97 : CAL ; Remplacement de MathGra par Array2OfReal
-07-01-98 : CAL ; Ajout de la methode DoMapping.
-07-01-98 : CAL ; Retrait de tous les "this->" inutiles
-21-01-98 : CAL ; Remplacement des Window->Position () par Window->Size ()
-27-01-98 : FMN ; PERF: OPTIMISATION LOADER (LOPTIM)
-12-02-98 : GG ; Reactivation du Redraw dans MustBeResized()
-23-02-98 : FMN ; Remplacement PI par Standard_PI
-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.
