I still think you're checking the wrong thing by looking at the rendered
output for 'various attributes/settings were propagated+used'. That
strongly suggests to me that you just want to inspect a trace/log just
to check the appropriate functions were called. As an addendum to that
you have a set of higher level integration tests that ensure that the
output is consistent with your expectations. You should not have to
duplicate Cairo's own testing, and it should be sufficient to include in
your testing.
