clippedline example status

Hello,

I was playing a bit with the clippedline example
(http://matplotlib.org/examples/pylab_examples/clippedline.html) and I
feel it is not working anymore.

From what I understand of the traceback I got, there may be something
evil happening after setting

self._marker = 's'

in the draw method. Maybe using the self.set_marker('s') is safer

Also, by reading some archived emails from this mailing list, it seems
that the purpose of this example became pointless because line clipping
is now implemented directly in matplotlib. Am I right ?

For what it's worth, I modified the clippeline.py example to make it
just serve the purpose of dynamically changing the appearance of the
line when zoom level is changing. I called t "zoom_adaptive_line.py" :

Would this script be an appropriate replacement for the clippedline
example ?

Best,
Pierre
