That'd be great. I just installed inkscape and xmllint on the non-bare
buildslave machine.

Done in r7863. To make use of it, do something like the following patch
(and don't forget to delete the baseline .pdf files from the repository):

-@image_comparison(baseline_images=['simplify_curve'])
+@image_comparison(baseline_images=['simplify_curve'],extensions=['png'])

That would require the Mac OS X buildslave to start working again too,
as I assume the backend actually requires the OS. And that would require
building on Snow Leopard to work, as I understand it.
