  12 // By default, the contentView does not occupy the full size of a framed

  14 // has done this by adding subviews directly to the root view. This causes
  15 // several problems. The most egregious is related to layer ordering when the
  16 // root view does not have a layer. By giving the contentView the same size as
  17 // the window, there is no longer any need to add subviews to the root view.
  18 //
  19 // If the window does not have a titlebar, then its contentView already has the
  20 // same size as the window. In this case, this class has no effect.
