Oh. Gentoo does something funny when it builds pycairo (1.4.0); the
resulting _cairo.so exports PycairoFontFace_FromFontFace and a lot of
other useful symbols.

I'd resort to C at this point; pycairo.h provides the wrapper we need
in the Pycairo_CAPI interface. (Of course it's possible to wrap that
struct with  ctypes  and query python for it with
ctypes.pythonapi.PyCObject_Import("cairo", "CAPI"). But it feels
wrong.)
