This function will create a new tspan element with the same attributes as the tref had and add the same text as a child. The tref is replaced in the tree with the new tspan. The code is based partially on sp_use_unlink Definition at line 571 of file sp-tref.cpp. References Inkscape::XML::Node::addChild(), Inkscape::XML::Node::attribute(), SPDocument::getObjectByRepr(), SPObject::parent, Inkscape::XML::Node::setAttribute(), sp_object_ref(), sp_object_unref(), sp_repr_parent(), sp_style_merge_from_dying_parent(), sp_style_merge_from_parent(), sp_tref_convert_to_tspan(), and SPObject::style.
