Cairo should already provide the needed support for iOS in the
Quartz backend. If that is the main backend used by the application,
Pixman should already be quite usable without NEON optimization,
as it will only be used for fallbacks. Of course it would be nice to get
NEON fast paths, if they can actually be used on that architecture.

An example/model of such a guide could be:

It gives you the whole sequence of commands needed to compile
the library (in the boxes) and explains what's happening and why.
