As far as I understand it (from pure Windows programming in Delphi, amongst
others), the dash patterns for line drawing in the windows GDI only has an
effect if the line width is 1 pixel.  If the line width is more than one
pixel, then you always get a solid line.  Different styles are possible for
the brush, however, so in normal windows programming it is possible to get
stippling effect.  But I don't know how well it is supported in Tkinter.
