DESCRIPTION
       The list of extension records at the specified offset in the specified
       widget_class will be searched for a match on the specified type, a
       version greater than or equal to the specified version, and a record
       size greater than or equal the specified record_size if it is nonzero.
       XtGetClassExtension returns a pointer to a matching extension record
       or NULL if no match is found. The returned extension record is owned
       by the widget class and must not be modified or freed by the caller,
