Additionally, as shown in the changes by Sean, you might need to define
some missing types or kill the code that relies on them (the main thing I
see in those patches is ATSUI, a legacy font backend).
Be warned that cairo-quartz used to call some functions that were not
exposed through the public API and this might be forbidden to applications
that are meant for the AppStore.
IIRC the backend was cleaned up so that these functions are only used if
(dynamically) detected as available, but I am not sure if this is allowed
by the store rules.
