Thanks for the thorough investigation.
Michiel: can you look into why the macosx backend is drawing the strokes
around the polygons? Probably as simple as inadvertently ignoring an
argument.
I'll look into the path simplification-related issues.

Yes. By far the worst of these behaviors is the macosx GUI output. I
could see the other ones just being the way it's supposed to look.
Here's a summary:
backend: macosx; path.simplify: (false|true) GUI => black borders to
drawn polygons (incl. contour region crossing lines, very bad)

I switched back to using the macosx backend, and it turns out that the
thin black lines surrounding the polygons (including crossing the
filled contour regions from one closed contour to another) only get
displayed in the GUI. PDF and PNG output look fine.

In both of these cases (path.simplify: True|False), the
Shot in the dark here, but what if you set the rcParam "path.simplify"
to False? There have been recent changes to that code.
Also, since the Agg backend doesn't have an associated GUI, you need to
use the savefig() command and provide a filename, rather than using show().

Um, yeah. So my response got bounced because of the attachment. Take 2:
For some reason my script bombed when I switched to the Agg backend,
trying to display to the screen (it said Figure has no method show())
So I output the plot as both a PDF and a PNG (still having backend:
agg in my rcfile
So you see this behavior if you switch to the Agg backend? That's the
backend used to generate the images in the gallery. If there's a
difference there, that would seem to suggest some tweaking of the macosx
backend (which is still relatively new) is in order.

I just installed the latest SciPy Superpack in order to get access to
the scipy.spatial.KDTree class, and discovered that for some reason
now when I use contourf() lines get drawn at the boundaries between
the filled contours. Additionally, there is always a single vertical
line crossing from each
