 i'm just thinking about it, so it is not a proposal at this time.

 i have not yet checked the matter in the sane source but, if we add 
 the api call to dll.c and not in the backend, what will happen?

  a) segfault
  b) SANE_STATUS_NOT_SUPPORTED

 ?

 if b, we would not need to update the backends. if a) then it
 is not the way to go.
 
 I do not like changing every backend. but if we can change little
 in dll/"real" 1.1 backends that would be fine.
