   FIXME for virtual list controls

  +1. clicking on the item with a mouse is awfully slow, what is going on?
      note that selecting with keyboard seems to be much faster
   => fixed HighlightAll() - iterating over 1000000 items *is* slow

   2. background colour is wrong?
 */

/*
   TODO for better virtual list control support:

   1. less dumb line caching, we should cache at least all those visible
      in the control itself and probably twice as many (we might also need to
      cache the first one always for geometry calculations?)

  +2. storing selections: we can't use an array to store the selected indices
      like right now as selecting all in a control with 1000000 items is not
      doable like this - instead, store selections as collection of individual
      items and ranges

   => wxSelectionStore

   3. we need to implement searching/sorting somehow

   4. the idea of storing the line index in the line itself is really stupid,
      we shouldn't need it - but for this we have to get rid of all calles to
      wxListLineData::GetFoo() and replace them with something like
        if ( IsVirtual()
            ... we have it ourselves ...
        else
            line->GetFoo();
