    bnc#862514: Handle corner case in slide sorter correctly.
    
    We should never return -1 when bIncludeBordersAndGaps is true; but that could
    have happened in a corner case:
    
    * export SAL_USE_VCLPLUGIN=gen
    * start LibreOffice
    * open a presentation with many slides
    * resize the window so that it shows the slides _exactly_, no slide is cut
      off in the slide sorter
    * point the mouse pointer into the left "Slides" sidebar (slide sorter) so
      that it does not cause any mouse-over effect (somehow between the left
      border, and the slides - there is space that can do this)
    * turn the mouse wheel all the way down so that the last slide is at the
      bottom
    * turn the mouse wheel up _once_
    * turn the mouse wheel down _once_ - it will look like the view does not
      change (the last but one is still at the bottom), but you can see the
      scrollbar jump to the top
    * and now you can again start turning the wheel all the way down to repeat
      the procedure :-)
