same data.
Note that wxWidgets follows the <em>STL philosophy</em>: when a comparison
-operator can not be implemented efficiently (like for e.g. wxImage's ==
+operator cannot be implemented efficiently (like for e.g. wxImage's ==
operator which would need to compare the entire image's data, pixel-by-pixel),
it's not implemented at all. That's why not all reference counted classes
provide comparison operators.
