commit e48b4275ceee82bd0eb128b2947302b9022e9c89
Author: Tomaž Vajngerl <tomaz.vajngerl at collabora.co.uk>
Date:   Mon Feb 19 21:47:04 2018 +0900

    report the saved mimetype when saving graphic + mime from stream
    
    When saving we need to determine which mime type to use for the
    graphic. Return this information back to the caller so the
    metadata can be written into the file if necessary.
    
    Also add function to determine the mime type from the XGraphic
    by converting it to a stream first (only then we can determine the
    format that will actually be used and written to the storage file.
