   now called much earlier/later than before; please move any exiting code
   from there to wxApp::OnInit()/OnExit()
 - also, OnExit() is not called if OnInit() fails
+- finally the program exit code is OnRun() return value, not OnExit() one
 - wxTheApp can't be assigned to any longer, use wxApp::SetInstance() instead
 - wxFileType::GetIcon() returns wxIconLocation, not wxIcon
 - wxColourDatabase is not a wxList any more, use AddColour to add new colours
