wxPython tickets on Trac

Hi, Robin et al,
Relatively recently I did test some pretty old wxPython trac tickets. I made a conclusion that a big
number of them should be closed as they are outdated.

However, I am not sure if I can just go ahead and close them myself or wait for Robin or someone else here
to go and close them. They are still appears to be opened.

Please advise. It would be nice to get rid of some old bugs that was sitting there forever.
Especially since there is almost time for wxWidgets 3.1 release…

Thank you.
