#   Hello2
#   ------
#   A version of the "Hello world" program which centers the
#   text in a window.
# 
#   The newwindow function creates a window, and setredraw associates
#   a redraw call-back function with the window. The show function
#   then causes the window to appear on screen.
# 
#   The call-back draw_window is passed the window and the
#   window's rectangle as parameters. It calls drawtext to
#   draw the words "Hello world" centered horizontally and vertically
#   inside that rectangle.
