       channel from one image pixel position to another,
Adverbs:
   PIXXY.........Image pixel position for first point of line
   PIX2XY........Image pixel position for last point of line
                 If both of these positions do not lie on the TV based
                 on the image to which they apply, thne the line will
                 not be drawn.  This does not require that they lie
                 inthe subimage actually displayed, just that they fit
                 on the TV.
