Cairo is not a GObject library, so introspection is fairly useless.
the only reason why Cairo has introspection data is for GObject
properties and signal marshallers, as well as Cairo types in exposed
in public API in other libraries; the Cairo type system is not mapped
to the GObject type system, so introspection cannot do much to
differentiate calls on, say, an image surface and an xlib surface.

for Cairo, you should always prefer native bindings — like pycairo, or
the cairo GJS module.
