  30  * Note on the layer mix with symbolic/ID-based interface:
  31  * You create a new layer with
  32  *    pLayerAdmin->NewLayer("A new layer");
  33  * This layer is automatically appended to the end of the list.
  34  *
  35  * The same holds true for layer sets.
  36  *
  37  * The interface for SdrLayerSet is based on LayerIDs. The app must get
  38  * an ID for it at the SdrLayerAdmin, like so:
  39  *   SdrLayerID nLayerID=pLayerAdmin->GetLayerID("A new layer");
  40  *
  41  * If the layer cannot be found, SDRLAYER_NOTFOUND is returned.
  42  * The methods with the ID interface usually handle that error in a
  43  * meaningful way.
  44  * If you not only got a name, but even a SdrLayer*, you can get the ID
  45  * much faster via the layer directly.
  46  *
  47  * @param bInherited:
  48  * TRUE If the layer/layer set cannot be found, we examine the parent layer admin,
  49  *      whether there's a corresponding definition
  50  * FALSE We only search this layer admin
  51  *
  52  * Every page's layer admin has a parent layer admin (the model's). The model
  53  * itself does not have a parent.
