// 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.
