Otherwise, would replacing the legacy W2K era IExtractImage & IExtractImage2
we've been using to format the extracted preview be appropriate now?
Does the Windows Vista era IThumbnailProvider interface [1] offer a cleaner way
to extract document previews without needing the backing rectangle being filled
white using the SolidBrush fillRectangle and black border?
Suggests the IThumbnaiProvider would more broadly handle the container for the
thumbnail--we'd now just have to give it the bitmap out of the archive (maybe
include Flat ODF as for bug 53534). And so improving the os/DE integration on
Windows?
