This filter implements a fix for scanners that have some columns
of pixels offset. Currently it only shifts every other column
starting with the first one down ch_offset pixels.

The Deinterlacer detects if data is in SANE RGB frame format (3 bytes/pixel)
or in Grayscale (1 byte/pixel).

The first ch_offset lines of data in the output are fudged so that even indexed
add odd indexed pixels will have the same value. This is necessary because
- the real pixel values of the columns that are shifted down are not

in the data for the first ch_offset lines. A better way to handle this would be to
- scan in ch_offset extra lines of data, but I haven't figured out how to do this
