The field-size is only one way to specify the limits for the scroll
bars. It is used as one of the inputs to the default scroll-bar-limits
method (in "ccl:library;scrollers.lisp"). You can either change the
field size with (setf (slot-value scroller 'field-size) ...) or
by writing a scroll-bar-limits method. The example at the end of
"ccl:library;scrollers.lisp" shows a scroll-bar-limits method.
You might also need to explicitly call update-scroll-bar-limits.
