well, i wanted to minimize the changes to front-ends, other than
dropping unknown frame types. also, this sets up a precedent for
backends needing to have 'modes' where they support historical
versions of the sane standard. in this case, that is not a problem,
but in the future, it might be.

are you proposing that we update every backend in sane with this
function- because they are all going to get their minor version number
bumped to 1, to match their new sonames...
