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
