-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.

-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
-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.

-************************************************************************/
-
-#define GER61351 //GG_15/12/99 Add SetBackgroundColor()
-// and BackgroundColor() methods
-
-
-#define IMP240100 //GG
-// -> Remove PixToRef() method ,use
-// instead the equivalent Convert() method.
-// -> Rename RefToPix() to Convert() method.
-// -> Remove the grid computation in Convert()
-// method. Use instead the NEW ConvertToGrid() methods.
-// Reason is the Convert() method is call by
-// StdSelect_ViewSelector3d_Pick() from
-// AIS_InteractiveContext() and it's not possible
-// to select an object vertex when the grid is active!
-// -> Remove grid echo marker definition
-// (reported in the viewer)
-// -> Add SetProjModel() methods.
-
-#define G003 //EUG 04-10-99
-// -> computed mode management
-// Add SetComputedMode(..) method
-// -> animation mode management
-// Add SetAnimationMode()
-// -> backfacing management
-// Add SetBackFacingModel() method
-
-#define G004 //VKH 15-11-99
-// -> Add Dump() methods
-// -> GG 07/03/00 Use the new MMSize()
-// method from Aspect_Window class.
-
-#define IMP210200 //GG Add Transparency() method
-
-#define IMP250200 //GG With SetDepth() method, when the requested
-// depth is < 0.,
-// move the view ref point and the eye,instead
-// only the eye.
-

-// without call before StartRotation().
-// This problem occurs when CTRL MB3 is maintain press betwwen 2 views.
-
-#define IMP250900 //GG Enable rotation around screen Z axis when
-// rotation begin far the center of the screen.
-// Thanks to Patrick REGINSTER (SAMTECH)
-// GG 21/12/00 Due to a regression on the previous specifications
-// this new functionnality is right now deactivated
-// by default (see StartRotation(...,zRotationThreshold)
-// method.
-
-#define BUC60952 //GG Enable to rotate around the view axis

-
-#define RIC120302 //GG Add a NEW SetWindow method which enable
-// to connect a graphic widget and context to OGL.
-
-#define IMP260302 //GG To avoid conflicting in Window destructor
