The fujitsu backend does setup the option descriptors at the time they
are accessed, and later uses them to correct the values set by the
front end. If XSANE sets the values before it has requested the
descriptions, that would be a problem. It would also be unusual.
There is also some logic in the fujitsu backend which attempts to keep
the y resolution equal to the x resolution. XSANE seems to counteract
this. The current development version removes the y-resolution option
