When the user is trying to insert a pivot table and the destination area
contains one or more non-empty cells, it launches a confirmation dialog asking
the user whether or not to overwrite the non-empty cells.  When this happens,
Calc should highlight the destination area to provide a visual clue to the
user.  When the destination area is off screen, it should move the visible area
to that area, but do so without moving the internal current cursor position,
similar to the way the reference dialogs do.
