value of the <integer expression> in the range 0 to 255, sets the bits in each adjacent
group of8 pixels to ON (1), or OFF (0).
The <first point setting> determines whether the first point of the line is to be plotted
(1) or not plotted (0).
Either of the parameters may be omitted, but not both. If a parameter is omitted, that
particular setting is not changed.
