  // Autosave only the window's bottom-right corner.

  // Autosave the whole window rect, i.e. both position and size.

// WindowSizeAutosaver is a helper class that makes it easy to let windows
// autoremember their position or position and size in a PrefService object.
// To use this, add a |scoped_nsobject<WindowSizeAutosaver>| to your window
// controller and initialize it in the window controller's init method, passing
// a window and an autosave name. The autosaver will register for "window moved"
// and "window resized" notifications and write the current window state to the
// prefs service every time they fire. The window's size is automatically
// restored when the autosaver's |initWithWindow:...| method is called.
// Note: Your xib file should have "Visible at launch" UNCHECKED, so that the
// initial repositioning is not visible.
