- IsSortOrderAscending() return value).

- Don't confuse this function with SetSortable() which should be used to
- indicate that the column @em may be used for sorting while this one is
- used to indicate that it currently @em is used for sorting. Of course,
- SetAsSortKey() can be only called for sortable columns.

- Sort (default) or don't sort the control contents by this column.
