Don't know, I use the latex, dvips, ps2pdf route.

    Stephan> Can you use `solid' objects in your pictures?

Yes, they are overlayed as I expect.

    Stephan> And does the same technique work with LaTeX+dvips as

See above.

Don't know. It should be possible. But I just applied the patches and
didn't look into them. Your idea sounds more stable than the way
its done now. Maybe you should propose it to Klaus Guntermann. 

In the meantime I played around a little bit more. If I include only
the actual layer within each step, I find this overwriting behaviour. 
I changed the code for the tpmultiinc command to remove the dependence
on repeat.tex. I can post it if anyone is interested.
