-// in wxMSW version 2.1.11 and earlier, wxIcon always derives from wxBitmap,
-// but this is very dangerous because you can mistakenly pass an icon instead
-// of a bitmap to a function taking "const wxBitmap&" - which will *not* work
-// because an icon is not a valid bitmap
-//
-// Starting from 2.1.12, you have the choice under this backwards compatible
-// behaviour (your code will still compile, but probably won't behave as
-// expected!) and not deriving wxIcon class from wxBitmap, but providing a
-// conversion ctor wxBitmap(const wxIcon&) instead.
