This would not break the sane api very hard and all backends would still<br>
|
||
work.Only a backend that does work this way will not work with an "old" frontend.<br>
|
||
<p>
|
||
So I think it would be ok. Should be no great thing for xsane to do so, but<br>
|
||
David has to confirm this first!<br>
