+// ClientView
+//
+//  A ClientView is a view representing the "Client" area of a Window. This is
+//  defined on Windows as being the portion of the window excluding the frame,
+//  title bar and window controls.
+//
+//  This abstraction is used to provide both the native frame window class
+//  (ChromeViews::Window) and custom frame window class
+//  (ChromeViews::ChromeWindow) with a client view container and dialog button
+//  helper. ChromeWindow is used for all dialogs and windows on Windows XP and
+//  Windows Vista without Aero, and Window is used on Windows Vista with Aero,
+//  and so this class allows both Window types to share the same dialog button
+//  behavior.
