Hi everyone,

When implementing undo for my plugin I noticed that setting an undo limit will 
cause Memory leaks since UndoStackItems are not deleted when exceeding the 
limit (unlike when using ClearList).
See mitkLimitedLinearUndo.cpp(and for that issue also 
VerboseLimitedLinearUndo.cpp) in the method SetOperationEvent:

  if (m_UndoLimit > 0 && m_UndoList.size() == m_UndoLimit)
  {
    m_UndoList.pop_front();
  }

Kind regards,

Bertram
