#   Lines
#   -----
#   The program creates three points using the pt function and
#   then draws lines between them.
# 
#   The lines are drawn using the default colour which is Black
#   and the defaut line width which is one pixel.
# 
#   Drawing will automatically create and show a window if there
#   is no currently visible window.
