/**
* A custom list UI, used by the completion choices list. If the number of
* completion choices is "large," it does a fast estimate of the preferred
* width and height of list items. This allows HTML renderers to be used (such
* as {@link CompletionCellRenderer}), with thousands of completion choices,
* with no performance penalty. With standard BasicListUI subclasses, this can
* cause very poor performance <b>each time</b> the list is displayed, which
* is bad for lists that are repeatedly hidden and re-displayed, such as
* completion choices. This is all because the calculation to get the
* preferred size of each list item, when it is displayed with HTML, is slow.
