tdf#126319 Correct area(s) on selection export

For shapes like TextFrames the export of the selected
object(s) to Bitmap needed to be adapted. It should
not reduce to minimal geometric necessary size.

While reduction seems good initially as an idea this
may change aspect ratio and expected size of the result
by cutting off visually empty areas, e.g. the text
distance areas to the shape's logical bounds.

This also needed to be adapted to multi-selections
accordingly.
