I started doing that, bug zecke convinced me to do it differently. It
looks like we _can_ expect at least equal sizing (which is what matters
to Render dumps) with Mac, indeed, if we use appropriate fonts and GTK+
theme. We could perhaps even get pixel-perfect rendering on many tests,
too.

We just need to make sure the theme is always the same. That should be
pretty easy to do.

Thanks for your email!
