Paged documents: rework zoom options (#6885)

Browse Source 
- Move zoom options from top menu to bottom config
- Add option to manually define zoom (relative to
  page width) and overlap (in percent)
- Add options to zoom to columns or rows, possibly
  with overlap. Add panning direction options when
  page forward in these modes
