  28 Using this class, you can find out:
  29 - SdrView* First/NextView()
  30   - All Views in which a model is displayed
  31   - All Views in which a certain page is visible (also as MasterPage)
  32   - All Views in which a certain object is visible (also as MasterPage)
  33 - SdrPageView* First/NextPageView()
  34   - All PageViews in which a model is displayed
  35   - All PageViews in which a certain page is visible (also as MasterPage)
  36   - All PageViews in which a certain object is visible (also as MasterPage)
  37 - vcl::Window* First/NextWindow()
  38   - All Windows in which a model is displayed
  39   - All Windows in which a certain page is visible (also as MasterPage)
  40   - All Windows in which a certain object is visible (also as MasterPage)
  41 You can specify if the selection is restricted to a certain page/object by
  42 choosing the corresponding constructor.
  43
  44 Among others, the following are considered:
  45 - Visibility state of the layer
  46 - Visible Layer of MasterPages
  47 - Multiple layer for group objects
  48
