243 * Ideas: How to overcome style invalidation nightmare

245 * 1. There is reference request dictionary, that contains
246 * objects (styles) needing certain id. Object::build checks
247 * final id against it, and invokes necesary methods
248 *
249 * 2. Removing referenced object is simply prohibited -
250 * needs analyse, how we can deal with situations, where
251 * we simply want to ungroup etc. - probably we need
