Default constructing a wxRegion created an object that unexpectedly passed IsOk() test in wxOSX. This was completely unexpected so don't do this and leave default constructed wxRegion invalid, as in the other ports. Update DoCombine() to be able to deal with the case of an invalid source region in a way consistent with the other ports. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@69459 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
