Principally those that exemplify the usage of Cairo by Mapnik, such that if
we can achieve decent performance improvements on those, then we know that
we can expect similar improvements in general for Mapnik. Those that are
slow to render are probably the best to look at - though we actually want
to identify ones where it is Cairo that is the bottleneck (for the
purposes of improving Cairo).
