changed its signature to take a const reference instead of a pointer which
simplifies the code and makes it safer as well

It sure would be nice if big complicated patches could be tested (or
at least compiled) on all the core platforms before being checked in,
especially in last-minute crunch times.

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
