Public Member Functions
	Graphic2d_ViewMapping ()
	Creates a view mapping with the following default values : XCenter = 0. YCenter = 0. Size = 1.
void	SetViewMapping (const Quantity_Length aXCenter, const Quantity_Length aYCenter, const Quantity_Length aSize)
	Sets new values for the view mapping <me>.
void	SetCenter (const Quantity_Length aXCenter, const Quantity_Length aYCenter)
	Sets new values for the view mapping center.
void	SetSize (const Quantity_Length aSize)
	Sets new value for the view mapping size.
void	SetViewMappingDefault ()
	Saves the current mapping which will be the reference value for the reset of the mapping done by the ViewmappingReset method.
void	ViewMappingReset ()
	Sets the value of the mapping to be the same as the mapping saved by the SetViewMappingDefault method.
void	ViewMapping (Quantity_Length &XCenter, Quantity_Length &YCenter, Quantity_Length &Size) const
	Returns the current mapping of the view <me>.
void	Center (Quantity_Length &XCenter, Quantity_Length &YCenter) const
	Returns the current center of the view <me>.
void	ViewMappingDefault (Quantity_Length &XCenter, Quantity_Length &YCenter, Quantity_Length &Size) const
	Returns the current reset mapping of the view <me>.
Quantity_Factor	Zoom () const
	Returns the zoom factor (CurrentSize/InitialSize).
