// FIXME: We use the empty string as domain name here. This tells the
// ConfigManager to use the 'default' domain for all its actions. We do that
// to get as close as possible to editing the 'active' settings.
//
// However, that requires bad & evil hacks in the ConfigManager code,
// and even then still doesn't work quite correctly.
// For example, if the transient domain contains 'false' for the 'fullscreen'
// flag, but the user used a hotkey to switch to windowed mode, then the dialog
// will display the wrong value anyway.
//
// Proposed solution consisting of multiple steps:
// 1) Add special code to the open() code that reads out everything stored
//    in the transient domain that is controlled by this dialog, and updates
//    the dialog accordingly.
// 2) Even more code is added to query the backend for current settings, like
//    the fullscreen mode flag etc., and also updates the dialog accordingly.
// 3) The domain being edited is set to the active game domain.
// 4) If the dialog is closed with the "OK" button, then we remove everything
//    stored in the transient domain (or at least everything corresponding to
//    switches in this dialog.
//    If OTOH the dialog is closed with "Cancel" we do no such thing.
//
// These changes will achieve two things at once: Allow us to get rid of using
//  "" as value for the domain, and in fact provide a somewhat better user
// experience at the same time.
