  #
  # The EditTransitionScene needs to have all the drawers
  # cleared from the class because it may still have
  # drawers from other things that this was executed.
  #
  # This is a product of using the classes to store the definitions
  # of scene. This means we need to change this so that it is much
  # easier to dup scenes.
