I've refactored hatching support to move the hatch design itself to the core, added support for them in the Agg and SVG backends, and simplified their usage in the PDF and PS backends. It should now be easier to add new hatch styles if anyone ever feels artistic.
In order to use the same general approach in all backends, the PS backend now uses the makepattern command rather than a loop to draw each hatch line. That may be a regression in certain situations (eg., old PS printers without enough memory). So those who were using the old PS backend with hatches should test the new approach and report any problems.

Hey Michael, this is really great. Did you get all this done this
morning or was this a holiday project 
The only problem I see is
that it looks like you forgot to fix the title in the hatch_demo.py!
The last major piece for patches is now gradient fills.

I've written a patch for the Mac OS X native backend to make use of the new hatching support; see patch #2497785 at
https://sourceforge.net/tracker/index.php?func=detail&aid=2497785&group_id=80706&atid=560722
I tested this with the new hatch_demo.py in SVN trunk, and it seems to work fine.

Thanks Michiel, I committed this patch to the trunk and closed the
