// This header file contains the entire definition and
// implementation of class BaseWindow. BaseWindow is an abstract
// base class that is used to define an interface between 
// terminal emulation code and a concrete display device. The
// class that implements the display code on some target device
// will be derived from this class, and will have to implement
// the pure virtual functions declared in this class.
