comparison pyink/domview.py @ 1284:cbcb91b196fa
Use svg:use to duplicate the key frame. The current inkscape will not keep the extra attributes when we break the reference. Therefore, we may modify the inkscape directly or implemnet a break by ourself. In addition, we may need to improve the duplication to sync the new-added objects to an existed group.
