This method is called to handle a named header that is found when reading buffer data from a stream. The return value should be TRUE if there are no errors.
Override this method to embellish the file format for your own derived wxMediaBuffer class. Always call the inherited method if your reader does not recognize the header. The default method will alert the user about an unrecognized header, but continue to read the file.
