The libdazzle library is a companion library to GObject and Gtk+. It provides various features that we wish were in the underlying library but cannot for various reasons. In most cases, they are wildly out of scope for those libraries. In other cases, our design isn't quite generic enough to work for everyone. The libdazzle project is heavily opinionated, and tends to gravitate towards design that matches the GNOME 3 human interface guidelines.
