Yes, just put the SANE_FRAME_RGBI in sane.h and hope it
will be made official later on..
When I suggested this some time ago someone replied that that the RGBI
term was already used in the videoworld and that this might lead to
confusion. However, when doing a websearch on RGBI it does not appear
to be used extensively for that (most hits where for old Commodore
monitors). So in the context of scanners/imaging devices it shouldn't
be too confusive.

That would be a good idea if you want to batch scan hundreds of
slides. But probably most people would like to get just one or a few
images as quickly as possible into the Gimp. For that it would
be nessacary to include the dust removal code also into the backend.
