  23  * - not all key mapping functions have been written
  24  * - allow dyn loading of curses library (extreme care should be taken for
  25  *   functions which can be implemented as macros)
  26  * - finish buffer scrolling (mainly, need to decide of a nice way for
  27  *   requesting the UP/DOWN operations
  28  * - Resizing (unix) terminal does not change (Win32) console size.
  29  * - Initial console size comes from registry and not from terminal size.
