+- wxDialog::OnOK/OnCancel() don't exist any more, use SetAffirmative/EscapeId()
+- wxPathList doesn't derive from (deprecated) wxStringList any more
+- wxGLContext class has no 1:1 coupling to a wxGLCanvas class any more.
+ As a consequence, the class interface changed largely.
+ Code updates, if any are required at all, are easy to accomplish though.
