    Depend on a Cairo release with cairo_surface_set_device_scale()
    
    We are checking for Cairo ≥ 1.12 and then do an additional check for the
    existence of the cairo_surface_set_device_scale() function because there
    were no stable releases of Cairo with it. Now that Cairo 1.14 is out, we
    can simply bump up the dependency.
