1. perform deep comparison for the classes for which it makes sense in the ports where this wasn't done yet 2. remove (shallow) comparison operators for the classes for which it does not make sense (such as wxBitmap) 3. makes wxBitmap use COW on all ports 4. adds wxObject::IsRefTo() 5. centralizes and improves COW docs git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@42752 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
