[sane-devel] New magicolor backend for inclusion in git

[Brian Shaver]

I'm having some trouble compiling with these changes committed. Below is the
error I'm getting. I'll admit I haven't actually looked into the source code
to confirm the change comes from this set of commits, but it seemed like it
would be related. I'm running Fedora 13, and I've been able to build from
the latest source as recent as 2011.01.12.

Thanks,
Brian ..
