; NAME:
; AdjustPosition
;
; PURPOSE:
;
; This is a program for interactively adjusting the plot position
; coordinates. The result of the function is a four-element floating
; point array of normalized coordinates, suitable for passing to the
; POSITION keyword of most IDL graphics commands.

;
; CATEGORY:
;
; Graphics
;
; 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.
