The old paper-model matrix approach has been superseded by a cleaner and smarter approach based on global/local maps. This resulted in a great code complexity reduction: check out the home page for further details. Parent-child relationship is no more tied to AdgContainer: dependencies between AdgEntities can now be expressed without a full-fledged container. AdgDim now uses internally four AdgToyText entities to render the quote. This has been made possible by the new parent-child APIs, simplyfing the rendering code a lot. A bunch of classes, most notably AdgRotable, AdgTranslatable and AdgPoint, have been superseded by the new global/local map approach and have been removed from the project.
