Don't know about iOS, maybe there are other things to take care of, but in
general you have to catch all the scrollbar events: scrollbarDrag,
scrollbarLineInc, scrollbarLineDec, scrollbarPageInc, scrollbarPageDec, and
change the location of the graphic accordingly. And if the field is editable you
also have to handle the up-arrow, down-arrow keys. And account for the fact that
the user can insert and delete lines.
