Re: tikz breaks topinsert

I don't know if it breaks topinsert, but I think such problems might be solved by restoring shipout, which I
do on every tikz inclusion:

\let\oldShipout\shipout\input tikz\let\shipout\oldShipout

This helped me to use tikz in quite customized environments without any negative effects in tikz itself, as
far as I tried/used it.
