At the moment, yes.

No! Don't do that. That value is (as far as we know) the units that the
SCANREQUEST values (offx/y, lenx/y) are given in. If you fiddle with that it
stasrt going off to scan the wrong area of the page.

Unless there is evidence it does more I'm not touching it. The windows
scanning program sets it once during the initiaisation and never touches it
again, no matter how many scans you do.
