	 The GDSII/OASIS file for which this operation is to be performed must be opened for
	editing either by opening it with QisLib_SetLoadMemory on or creating a new file
	using QisLib_NewGDSII/QisLib_NewOASIS.

	opened cell.
	- This function works for newly added as well as original data in the file.
	- QisLib_SetVectorHandle has to be turned on in order to get handles to data when
	vector data are returned to the user's program via the callback function.
	- QisLib_SetAddVectorHandle has to be turned on to get handles to data when they are
	added to the GDSII/OASIS file.
