status bar - please support showing dynamic X & Y location of pixel under the cursor

Hi:

In the next version of "eog" could you please support showing dynamic X 
& Y location of the pixel under the cursor, in the status bar.

Showing the actual value of pixel would be great too, if not too much 
trouble.  That cross-check would ensure the cursor is positioned at the 
correct X & Y location.

        ------

BONUS POINTS  (and virtual beerz) awarded if you can hit a key (F1 is 
easy) to append the above data to a text file ("eog.txt" comes to 
mind).  Perhaps if the SHIFT key is activated, upon hitting the F1 key 
the appending is continuous (upon any change of X and/or Y), until the 
F1 key is hit again to toggle continuous mode OFF.

The purpose is digitizing single points, or continuous curves. Quick and 
easy, like the rest of eog !

Thanks!
