"+" Enlargement with "Next" and "Previous"

[Nelson Max <max cs ucdavis edu>]

I use "Next" and "Previous" to look at al the images in a directory with 
EOG, and often I want to use the same enlargement for all of them. 
However, when I click "Next" or "Previous" my enlargement setting goes 
back to the default without any scale change, and I have to click "+" 
again. I would prefer it if the enlargement settings were preserved when 
I go between images.
