 // To use the iterators:

 // Create a stepping iterator and end iterator by calling
 // LayerIterator::Begin() and LayerIterator::End() and passing in the
 // list of layers owning target RenderSurfaces. Step through the tree
 // by incrementing the stepping iterator while it is != to
 // the end iterator. At each step the iterator knows what the layer
 // is representing, and you can query the iterator to decide
 // what actions to perform with the layer given what it represents.
