 /** @brief Read the XML tree of the content of an ODT file.
  *
  * The OdfDrawReader is used to traverse (read) the draw contents of
  * an ODF file using an XML stream reader.  For every XML element that
  * the reading process comes across it will call a specific function
  * in a backend class: @see OdfDrawReaderBackend.  The OdfDrawReader
  * is used as a common way to read draw content and is called from all
  * readers for different ODF formats.  @see OdtReader, @see OdsReader,
  * @see OdpReader.
