-// A LayoutManager adapter that allows clients to specify a minimum and/or a
-// maximum preferred size. The actual layout will be delegated to the
-// LayoutManager owned by this. i.e. |this| can be used to override the
-// preferred size returned by a View.
-//
-// By default the SizeRangeLayout is configured to own a FillLayout but this can
-// be overridden with SetLayoutManager().
-//
-// Example use case :
-//
-//  Suppose you wanted a Label to take up a specific size of (50, 50) even
-//  though the label's preferred size was (25, 25).
-//
-// Example code:
-//
-//  Label* label = new Label(kSomeDummyText);
-//  View* container = new View();
-//  container->AddChildView(label);
-//  SizeRangeLayout* layout = new SizeRangeLayout();
-//  layout->SetSize(gfx::Size(50, 50));
-//  container->SetLayoutManager(layout);
