In this callgrind -- see line# 47060

Each of the 2642 items  loaded in the Autocorrect listbox's GUI with
SvLBoxString::InitViewData() cost both a GetTextHeight() and more expensive
GetTextWidth() call.

As suggested comment 23 the GetTextWidth() could again be controlled by testing
size of the list, assigning a fixed width when list is > some number maybe
~300.

Also, since this controls all GUI listboxes, we can't just make the text height
fixed, but guess we could include within the same list size testing and save
that cost as well?
