// Class Description:
// Text, i.e., a character string, is used to visualize various kinds of 
// description, particle name, energy, coordinate names etc. Text is 
// described by the class G4Text. The following constructors are supported: 
// 
//      //----- Constructors of G4Text
//      G4Text (const G4String& text);
//      G4Text (const G4String& text, const G4Point3D& pos);
// 
// where the argument text is the text (string) to be visualized, and pos 
// is the 3D position at which the text is visualized.  Note that class 
// G4Text inherits G4VMarker.  Size of text is recognized as "font size", 
// i.e., height of the text. All the access functions defined for class 
// G4VMarker are available. In addition, the following access functions 
// are available, too: 
// 
//      //----- Set functions of G4Text
//      void G4Text::SetText ( const G4String& text ) ;
//      void G4Text::SetOffset ( double dx, double dy ) ;
// 
//      //----- Get functions of G4Text
//      G4String G4Text::GetText () const;
//      G4double G4Text::GetXOffset () const;
//      G4double G4Text::GetYOffset () const;
// 
// Method SetText() defines text to be visualized, and GetText() returns 
// the defined text. Method SetOffset() defines x (horizontal) and 
// y (vertical) offsets in the screen coordinates. By default, both offsets 
// are zero, and the text starts from the 3D position given to the 
// constructor or to the method G4VMarker:SetPosition(). Offsets should be 
// given with the same units as the one adopted for the size, i.e., 
// world-size or screen-size units.
