    tdf#107392 ODF import: fix z-order sorting of SVG images
    
    The problem was that in case the document has shapes where the order
    does not match the z-index order, so sorting is needed, then sorting
    failed to take the multi-image feature into account. E.g. SVG images
    have a PNG fallback, but at the end of the shape import the PNG
    fallback is removed, which means the "actual" (not the "wished") z-index
    of the shapes after the SVG image has to be adjusted.
    
    Without this happening SvxDrawPage::getByIndex() (or in case of Writer,
    SwTextBoxHelper::getByIndex()) will throw when the importer calls
    getByIndex(3) but we only have 3 shapes. This results in not honoring
    the z-index request of the remaining shapes.
    
    Regression from commit 44cfc7cb6533d827fd2d6e586d92c61d7d7f7a70 (re-base
    on ALv2 code. Includes (at least) relevant parts of:, 2012-10-09), from
    the

    part.
