So the user interface might look something like this:
pdf = PdfPages('filename.pdf')
fig=figure()
# ...
pdf.savefig(fig)
pdf.annotate(123,456,'my text here',fontsize=12,font='Helvetica')
pdf.close()
Should the coordinates be raw PDF points measured from the bottom left
corner, or passed through the figure transformation (or something else)?
What sort of font properties would you expect to be allowed?

I think that's what the pdf backend would end up doing internally, at
least if anything like coordinate transformations or any interesting
font properties need to be supported. It sounds like a fairly easy
change.
While we're discussing multi-page pdf files, would it be useful to have
pyplot-level support for them? It shouldn't be too hard to have pyplot
track your currently open pdf file and make, say, savefig with no
arguments direct the output to that. I personally don't have a use for
that, but do you think it would be a useful part of pyplot?

Hi,
I'm hoping to elicit the help of a developer who can fix the last
remaining failing test on the Mac buildslave. In a nutshell, there looks
to be a regression with the interaction between Axes.autoscale_view()
and the xunits kwarg of Axes.plot(). I have posted a bug report at
https://sourceforge.net/tracker/?func=detail&aid=2846058&group_id=80706&atid=560720
I'd like to ask for a bit of help fixing this one, because I'd then like
to work on a few more things, which I think will be easier (mentally, at
least), if we have all tests passing on at least one platform.
* borrow (and maybe extend) scipy's known failing test decorator so that
known issues don't elicit test failures. (E.g. font placement
differences between Ubuntu and Mac OS X. see
https://sourceforge.net/tracker/?func=detail&aid=2843243&group_id=80706&atid=560720
for more info.)
* automatically send notifications to somewhere (to where?) when tests
start failing
* write documentation for developers and patch submitters describing how
to write unit tests for MPL -- both image based and more traditional kinds.
* get my Windows virtual machine doing this same dance
* automatically upload daily builds of binaries for Win and Mac
* adding more machines to the buildbot system
Of course, I'm happy to help if anyone wants to contribute to these or
other ideas. I plan to slowly chip away at this stuff over the coming
weeks and months.

I could use that too :).
