REVISION SUMMARY
  The VariableToolTip is supposed to resize vertically as much as can fit
  in the window whenever the content changes. It was not working because
  the m_itemHeight was 0 which was because the QTreeView::indexRowSizeHint
  was called with index from m_model instead of m_proxy.
  
  Same for the initial selection below.

TEST PLAN
  Debug some program, stop execution and hover over some variable. Expand
  some subitems - the tooltip should be resizing.

REPOSITORY
  R32 KDevelop
