- Height of the listbox should be adjust when LBS_OWNERDRAWFIXED is set
  and not if LBS_OWNERDRAWVARIABLE is set, previously it was not adjusting
  the size in both cases.
- When the caret index change, items repainting need tp be in this
  order
  a) Paint old caret item without the focus
  b) Paint old caret item without the selection
  c) Paint new caret item with the selection
  d) Paint new caret item with the focus.
- When repainting the listbox, we should paint all items regarding if
  they are slected or not and then paint after the focus item. So focus
  item will end out being painted twice. (That's what Windows does).
