- * Image objects can be shared between ImageActors. This is practical if you have a visual element on screen
- * which is repeatedly used. An example would be a button background image.
- * The image resource is discarded when all ImageActors using the Image object are discarded or in case they
- * were created with ReleasePolicy::Unused, taken off stage.
- * Note: if a resource was shared between Image objects it exists until its last reference is gone.
