A WMF may have EMF with EMF+ actions embedded. When we read that,
we drop drawing non-EMF+ actions if we use EMF+. But EMF+ actions
are stored as MetaCommentAction in the metafile, and WMF writer
(unlike EMF) writer simply ignores comments. So when writing WMF,
make sure to read non-EMF actions so that something is written.
