-/**
- * The manager for loading Npatch textures.
- * It caches them internally for better performance; i.e. to avoid loading and
- * parsing the files over and over.
- *
- * Cache is not cleaned during app lifecycle as N patches take considerably
- * small space and there's not usually a lot of them. Usually N patches are specified in
- * toolkit default style and there is 1-2 per control that are shared across the whole application.
