[ Version ( since = "1.32.4" ) ]
public void changed ()
Forces a change in the context, which will cause any `PangoLayout` using this context to re-layout.
This function is only useful when implementing a new backend for Pango, something applications won't do. Backends should call this function if they have attached extra data to the context and such data is changed.
