In bug 58190, picture handling for Common SL was changed from using raw integers to enums. The same changes should be made to Common SS.
These might be able to be moved to o.a.p.common.usermodel.PictureType o.a.p.sl.usermodel.PictureData.PictureType o.a.p.ss.usermodel.Workbook.PICTURE_TYPE_* o.a.p.hwpf.usermodel.PictureType o.a.p.xwpf.usermodel.Document.PICTURE_TYPE_*
