-// The scoped_* classes in this file help to make GDI settings easier. The
-// constructors of these classes sets/selects provided new value into the
-// context (HDC) and stores the original value in a class member. The
-// destructors restore the context to its original state by setting the stored
-// value back.
-//
-// Example usage:
-// {
-//   // Selects the font into hdc.
-//   scoped_select_object select_font(hdc, ::GetStockObject(DEFAULT_GUI_FONT));
-//
-//   // Changes the bk mode in hdc.
-//   scoped_set_bk_mode set_bk_mode(hdc, TRANSPARENT);
-//
-//   // Changes the bk color in hdc.
-//   scoped_set_bk_color set_bk_color(hdc, kBackgroundColor);
-//
-//   /* Do painting operations with hdc here */
-//   ...
-//
-// }  // scoped_* goes out of scope, restoring hdc back to its original state.
