[sane-devel] hp4200c backend

[Frank Zago]

Hi,

I've been loaned a hp4200c for some time. So I cleaned up the apparently 
orphaned backend. Right now the backend does:
   - preview
   - 75, 150, 300, 600dpi in color mode
   - gamma
and that's it! No black&white, no grayscale, no more resolutions.
I'm not going to add more time into it. It does not much, but it works well.
I was wondering if that's enough to submit it. Comments?

Frank.
