/*======================================================================
       Routines for painting the screen
          - figure out what the terminal type is
          - deal with screen size changes
          - save special output sequences
          - the usual screen clearing, cursor addressing and scrolling


     This library gives programs the ability to easily access the
     termcap information and write screen oriented and raw input
     programs.  The routines can be called as needed, except that
     to use the cursor / screen routines there must be a call to
     InitScreen() first.  The 'Raw' input routine can be used
     independently, however. (Elm comment)

     Not sure what the original source of this code was. It got to be
     here as part of ELM. It has been changed significantly from the
     ELM version to be more robust in the face of inconsistent terminal
     autowrap behaviour. Also, the unused functions were removed, it was
     made to pay attention to the window size, and some code was made nicer
     (in my opinion anyways). It also outputs the terminal initialization
     strings and provides for minimal scrolling and detects terminals
     with out enough capabilities. (Pine comment, 1990)
