*   FILE: window.h
* AUTHOR: CAL
* DATE: 25 April 1993
* PURPOSE:
*   A window is a rectangular screen object which has a border and
*   may have a title bar.  The area contained inside the border and
*   title bar is called the client area.  The client area of a window
*   is, itself, a Display.  This means that you can draw on it
*   and it can contain ScreenObjects, such as buttons and windows.
