1. Yes - the preview is typically a metafile
2. This is rather academic as none such exist, but yes, the
preview only requires the caller to understand its format.
However, opening the document itself requires structured
storage, e.g. COM, so the point it _really_ moot. You
just can't get the preview without COM.
