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?
