Idiomatic equivalent of using cairo_surface_reference?

[inklesspen]

I have a C codebase where I will sometimes call cairo_surface_reference to get an independent reference to a surface. What is the equivalent way to do this in Rust? Rust's references are a different sort of thing than cairo's reference counting, I think…

clone() on surfaces is gives you a new reference via cairo_surface_reference(). It's not an independent reference though: it points to the same underlying surface, just like in C.

ah, very good; thanks!
