file_gamma affect how the image is actualy writen to a file.
display_gamma adjust the preview display.

For a PNG, it sets the gamma chunk of the file. For other formats that 
don't have such a mechanism, it adjust the pixels values according to 
the set value.

Idealy, file_gamma should be set at the same value as display_gamma and 
assumed_gamma.
