------- Additional Comments from Nikolas Zimmermann <zimmermann at kde.org>
Finally it does not leak anymore! The problematic area was SVGElementInstance,
it always ref()'ed the correspondingUseElement so these never got deleted, once
expandUseElementsInShadowTree() was executed. No new regressions - <use> feels
much more stable today (ie. carto.net/window.svg works _perfectly_ now - no
bugs!), no new leaks. All fine :-)
