(TV-DRAW-LINE X0 Y0 X1 Y1 ...) should draw a line from the point X0, Y0 to
the point X1-1, Y1-1.  This makes it easier drawing lines to edges of pieces
of paper, etc. which work this way.  

In addition, if one sends a window a DRAW-LINE message where one of the
x coordinates is the right margin or one of the y coordinates is the bottom
margin, truncation does not happen correctly.  I think the DRAW-LINE method
may be expecting TV-DRAW-LINE to behave as I mentioned above.
