Without copy ctor copying masks simply crashed because the same pointer was deleted twice. Also added a (completely trivial but better than nothing...) unit test for wxBitmap to check that copying masks does work now. Closes #11854. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@63774 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
