[sane-devel] Epson 4490

Hi,

as soon as I get a Avision based Minolta Elite 5400 which also has
a infrared channel I plan to add such support to the avision backend.

The data processing will (e.g. dust removal) will be most probably
added to the image library exact-image:

I'll not look out for any patents on the way because aside we do not
have legal software patents here in Germany I doubt a patent in
filling areas where you have IR spikes with the surrounding area
(and simillar techniques) will have much effect.
