There is a problem with this example
Seemingly the GD library being used here does not support drawing thick lines outside the drawing area as expected. If anyone can suggest how I might fix this problem (without resorting to polygons) I would appreciate it. ajcumming@gmail.com
We can start and end lines outside the confines of the surface.
