 /** @brief A default backend for the OdfDrawReader class.
  *
  * This class defines an interface and the default behaviour for the
  * backend to the ODF draw reader (@see OdfDrawReader). When the
  * reader is called upon to traverse a certain XML tree, there will
  * be two parameters to the root traverse function: a pointer to a
  * backend object and a pointer to a context object.
  *
  * The reader will traverse (read) the XML tree and for every element
  * it comes across it will call a specific function in the backend and
  * every call will pass the pointer to the context object.
  *
  * Each supported XML tag has a corresponding callback function. This
  * callback function will be called twice: once when the tag is first
  * encountered anc once when the tag is closed.  This means that an
  * element with no child elements will be called twice in succession.
