I would prefer to have an option that allows to negotiate returned 
format in terms of MIME types (with some MIME type reserved to the 
standard SANE frame format).

Please notice, sane_get_parameters cannot be implemented (or should just 
return requested, not the actual image parameters) if this option is 
active, because sane_get_parameters may require at least partial 
decoding of the image, returned by the scanner.
