 /*! \class TEScreen
 
     \brief The image manipulated by the emulation.
 
     This class implements the operations of the terminal emulation framework.
     It is a complete passive device, driven by the emulation decoder
     (TEmuVT102). By this it forms in fact an ADT, that defines operations
     on a rectangular image.
