georeferencing the gif image

[Michael Anderson]

I had a script that reports the coordinates, so I put it in an extension. 
The extension is called "Bounding Box". It will add a button with a box to 
the end of the button bar. Click it and it will pop up the coordinates for 
the current view extent in a message box. You can copy the coordinates from 
the message box and paste them into your map file. I have had .avx files get 
corrupted by email, so I zipped it. Hope it is useful to someone.
