This patch is based on #55578, [1] and [2]. Now it's possible to easily embed other documents (not only Office types) within Excel. As the VML-Drawings are a bit difficult to implement, I've decided to workaround the embedding icons/previews via a background fill - at least the elements are shown in Libre Office 5 and Excel Viewer ... although they haven't got a function there. Only a full office installation can open the embedded elements. [1] http://stackoverflow.com/questions/40382369 [2] http://stackoverflow.com/questions/16910503
