[cairo] User font callbacks and user data

I noticed there were some user-font callbacks added in 1.8:
I'm trying to implement these in a scripting language but I'm having
trouble because unlike the other callbacks these do not seem to have a
"user data" parameter. This is necessary to proxy the C function call
to a function in the scripting language.
At first I was thinking I could set a user data on the font face but
then I realized that might not work because when the callbacks are
called they are using a scaled font type and not a font face.
Now I could be thinking about this incorrectly and I admit I don't
exactly know what these functions are used for because I haven't tried
using them in an application. Are these functions meant to be set
per-font-face or are they meant to be global? I'm thinking they are
per-font-face which means I need to associate some user data with the
callbacks. Any ideas?
