Synopsis:
    #include <graph.h>
    void _FAR _settextwindow( short row1, short col1,
                              short row2, short col2 );

Description:
    The _settextwindow function sets the text window to be the rectangle
    with a top left corner at (row1,col1) and a bottom right corner at
    (row2,col2).  These coordinates are in terms of characters not pixels.

    The initial text output position is (1,1).  Subsequent text positions
    are reported (by the  _gettextposition function) and set (by the
     _outtext,  _outmem and  _settextposition functions) relative to this
    rectangle.

    Text is displayed from the current output position for text proceeding
    along the current row and then downwards.  When the window is full, the
    lines scroll upwards one line and then text is displayed on the last
    line of the window.

Returns:
    The _settextwindow function does not return a value.
