Thanks for fixing this -- Apple's Preview also showed the broken files
with no problems.

Hi all,
I noticed that `ginput` no longer works (tested with SVN trunk). Is
this a known problem?
Kind regards,
Stéfan

It seems like a blip because it is up (for me) now
JDH

I'm getting a 404 error from http://matplotlib.sf.net/
Is this just Sourceforge suffering an outage or did the content 
accidentally get removed?
Cheers,
Mike

Thanks for taking this on. That was completely my bad -- I put that 
code in there as a reasonable approximation and meant to go back and fix 
it, but it fell through the cracks.
One small note -- the PDF output was broken for acroread (but strangely 
not for xpdf), since it was outputting 8 values rather than 6 for the 
converted quadratic curves. I've fixed this in SVN.
Cheers,
Mike
