I'm not going to make a case for being able to select a line that is out of
view in the current scrolling list, but I *would* like to make the case that
if you select a line via script that the field should scroll only until it
is shown in the list and not attempt to center it. For example, if a field
displays 4 lines-worth of text and it has 8 lines of text in it, and it is
fully scrolled to the top, if you execute "set the hilitedLines of field 1
to 7", the field should scroll three lines up and only display lines 4-7 of
the field with line 7 highlighted. Similarly if you then execute "set the
hilitedLines of field 1 to 2", the field should scroll so that lines 2-5 of
the field are highlighted.

I think that it is the unnatural behavior of having the hilite go to the
center of the list that is at issue here.
