AdjustPosition
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.

position = AdjustPosition(startingPosition)
startingPosition - A four-element array of normalized coordinates
of the form [x0, y0, x1, y1].
position - The adjusted plot position. A four-element array of normalized coordinates.
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.
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.
