HISTORIQUE DES MODIFICATIONS :
--------------------------------
00-09-92 : GG ; Creation.
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.
-24-09-98 : CAL ; Ajout d'un parametre a V3d_View::SetPlotter.
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.
-13-06-98 : FMN ; PRO14896: Correction sur la gestion de la perspective (cf Programming Guinde)
29-OCT-98 : DCB : Adding ScreenCopy () method.
-10-11-99 : GG ; PRO19603 Add Redraw( area ) method
-IMP130100 : GG
--> Don't increase too much the ZSize.
--> Initialize correctly the Z clipping and D cueing
-planes.
-IMP100701 : SZV ; Add ToPixMap() method
-
REMARQUES :
-----------
About FitAll() multiple. This probleme is caused by missing
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.
