Subject: [PATCH] rhbz#1326602 avoid exp. bg bitmaps from deleted slides
ODF export uses SvxUnoBitmapTable (impl. of
com.sun.star.drawing.BitmapTable) to create fill bitmap styles. That
returns all XATTR_FILLBITMAP items that are in the document's pool. So
we ensure that bitmaps that are only used on deleted (either explicitly
or by undoing their insertion) slides are not in the pool.
