Calling Sequence



      position = AdjustPosition(startingPosition)

Optional Inputs



      startingPosition - A four-element array of normalized coordinates
            of the form [x0, y0, x1, y1].

Outputs



      position - The adjusted plot position. A four-element array of normalized coordinates.

Input Keywords



      GROUP_LEADER - The group leader of this program. This keyword
            is required to ensure modal operation when calling from
            another widget program.
      TITLE - The title of the window. "Adjust Plot Position in Window..." by default.
      XOFFSET - The X offset of the program on the display. Calculated from the
            upper left-hand corner of the display.
      YOFFSET - The Y offset of the program on the display. Calculated from the
            upper left-hand corner of the display.

Output Keywords



      CANCEL - Returns a 1 if the user selects the Cancel button. Returns 0 otherwise.
            Note that if the use cancels, the "position" parameter is set to the value of
            the "startingPosition" parameter.
