Yes, Gtkairo uses CFFI. Other backends can use whatever FFI they want
(the Beagle backend uses some OpenMCL-specific FFI as far as I
know). The Gtkairo backend uses various GTK and Cairo libraries, but I
admit that I do not fully know which ones.

No, that's because McCLIM as a whole does not mandate any specific FFI
- McCLIM is device-independent, and does not necessarily require the
use of FFIs, so any backend that needs to talk to C code needs to do
the FFI work itself.
