Prevent ourselves from exponential slowdowns, as demonstrated by svg/custom/pattern-nested-reference.html, the evil testcase from Said (very valuable one, thanks! :-) The invalidation logic itself is already tracking visited renderers, and is protected from cycles, but the actual drawing is still very inefficient, as we have to create 100k+ tile ImageBuffers here, w/o caching...
