polar_demo output

I think this is a known bug (and maybe a bug should be filed so it doesn't get lost).

Most of the backends don't have support for clipping which would be required for this to work.

Cheers,

A minor correction -- all the backends support rectangular clipping --
but only agg supports polygon clipping currently. The polar axes uses
a polygon approximation to a circle for the axes border which is used
to clip the lines. I think this would be fairly easy to add to ps,
pdf, and svg since i think they all have support for polygon clipping.
I'm not sure what the cairo status is.

I'm not sure about the cairo backend in matplotlib. But cairo itself
definitely has very good for polygon, (and curve-based path),
clipping. So it should be extremely trivial to add that to the cairo
backend in matplotlib if it's not there already.

And I'd be glad to help anyone doing this if they got stuck.
