Looks good so far, but seems to be rather a dirty hack... also, as you
mentioned, this only works for quant=1.

I don't think this is right. The whole point is that the range given
by scanimage -h differs from what it will eventually accept. For 1000
CCD pixels, I can give a width of 1000 (and it will scan 1000) even
though scanimage -h says 0..999 for both left and width.

Exactly.
