* Updates \a o_current to the latest version of the symbol available
* in the symbol library, while preserving any attributes set in the
* current schematic. On success, returns the new OBJECT which
* replaces \a o_current on the page; \a o_current is deleted. On
* failure, returns NULL, and \a o_current is left unchanged.
*
* \param [in] w_current The GSCHEM_TOPLEVEL object.
* \param [in,out] o_current The OBJECT to be updated.
*
* \return the new OBJECT that replaces \a o_current.
