    Conditionally depend on Pango 1.44.4
    
    We're using newly introduced Pango API, but we're not doing a version
    check on it. One option is to force a Pango ≥ 1.44.4 dependency; another
    is to do a compile time check and only use the new API if we're building
    against a new enough Pango.
