There are a few regressions around drawinglayer objects that might be related and need a lot of debugging. This also involves chart2 regressions around copy&paste.

this is almost two years old.
5 bugs have accumulated and been fixed.
I'm closing this to prevent old unneeded meta-bugs cluttering the bug tracker.
Markus, please re-open if you think this is still needed.
