  27 Using this class, you can find out:
  28 - SdrView* First/NextView()
  29   - All Views in which a model is displayed
  30   - All Views in which a certain page is visible (also as MasterPage)
  31   - All Views in which a certain object is visible (also as MasterPage)
  32 - SdrPageView* First/NextPageView()
  33   - All PageViews in which a model is displayed
  34   - All PageViews in which a certain page is visible (also as MasterPage)
  35   - All PageViews in which a certain object is visible (also as MasterPage)
  36 - vcl::Window* First/NextWindow()
  37   - All Windows in which a model is displayed
  38   - All Windows in which a certain page is visible (also as MasterPage)
  39   - All Windows in which a certain object is visible (also as MasterPage)
  40 You can specify if the selection is restricted to a certain page/object by
  41 choosing the corresponding constructor.
  42
  43 Among others, the following are considered:
  44 - Visibility state of the layer
  45 - Visible Layer of MasterPages
  46 - Multiple layer for group objects
  47
  48 Not considered are:
  49 - Whether the pages/objects were already painted or if an Invalidate is still pending
  50 - Whether the pages/objects in a Window are in a visible region
