Last week I asked how you'd reopen a metafile to add some more stuff on the
end.  Here's a summary of the responses I received:

Nothing!

After a bit more reading of Petzold and the SDK manual, I've come to the
conclusion that the line I quoted about GetMetaFile making a metafile 
available for modification is in error.  You can't do it other than
by replaying the whole thing into a new metafile, a very slow process.
(I'd still love to be contradicted...)

Petzold says that metafiles are mainly used for transferring things to
the clipboard, not for a program's own use.  That makes sense:  there's
just too much missing for them to be usable.
