      Thanks for the help -- I'll look tonight.

      I was thinking no undo because this is a one-time function, but you
      are reminding me I need a warning before-hand. The function needs to
      be able to work on a section of the map -- think of taking an
      Icosohedral projection & changing it to a pseudo-Mercator -- you'd
      work on each of the points separately (and as I'm envisioning it,
      work on the left side of each separate from the right)

      I think that point-items like symbols should be moved over, based on
      the position of their reference point.
