Not quite: a WindowPeek is a pointer to a WindowRecord, so you'd need
something like
	windRec := WindowPeek(yourWindowPtr)^;
Similarly, FrontWindow returns a WindowPtr (which you can convert to a
WindowPeek), not a WindowRecord.  Beware: FrontWindow returns the frontmost
VISIBLE window: it may return nil.
