   6 /*
   7     The basic idea is to have an interface which gives all relevant list
   8     processing functions, and can be used by the listbox to browse trough
   9     the list.
  10
  11     The listbox directly uses the implemented cursor. It tries hard to avoid
  12     iterating trough the (possibly very large) list, so it should be O(1),
  13     i.e. the performance should not be influenced by the size of the list.
  14
  15     The list interface knows how to draw the current entry to a specified
  16     offset. Different interfaces can be used to adapt different lists,
  17     pre-filter lists on the fly etc.
  18
  19                 cursorSave/Restore is used to avoid re-iterating the list on redraw.
  20                 The current selection is always selected as cursor position, the
  21     cursor is then positioned to the start, and then iterated. This gives
  22     at most 2x m_items_per_page cursor movements per redraw, indepenent
  23     of the size of the list.
  24
  25     Although cursorSet is provided, it should be only used when there is no
  26     other way, as it involves iterating trough the list.
