    tdf#142361 export: prevent shadow to rotate with shape
    
    OOXML has the feature to rotate a shadow together with the shape. The
    associated attribute rotWithShape has the default value 'true'. So
    if this attribute is missing, MS Office shows the shadow rotated. As
    LibreOffice never rotates a shadow, we need to write this attribute
    always. Because LibreOffice cannot rotate shadows, the error is only
    visible in MS Office.
    
    Here the attribute is added for the case of documents, which have no
    InteropGrabBag or no effects in it.
    
    When a shadow is generated in MS Office, MSO adds the attribute with
    value 'false' (0) to the file. MS Office has no UI to set this
    attribute. Problem is with cases, where the document comes from
    MS Office, has effects in InteropGrabBag, but the shadow was set in
    LibreOffice. To add the attribute in such cases too, bug tdf#142858
    has to be fixed.
