// This class provides a wrapper for the GNOME D-Bus API for querying the
// current display (monitor) configuration, and for applying a modified config.
// This wrapper never blocks the caller thread - the caller provides a
// OnceCallback to receive the current config. The caller can modify the
// returned GnomeDisplayConfig structure, and then ask GNOME to apply the
// changes. Note that applying a display config will take effect immediately,
// but will also cause GNOME to display a warning which allows the user to keep
// or revert the changes.
//
// Instances of this class only support a single callback at a time - later
// requests will cancel earlier ones. Changes to GNOME's display config
// should be infrequent, and if multiple operations are ongoing, only the
// latest operation should take effect.
