'GI.Gst.Objects.DynamicTypeFactory.DynamicTypeFactory' is used to represent a type that can be
automatically loaded the first time it is used. For example,
a non-standard type for use in caps fields.

In general, applications and plugins don\'t need to use the factory
beyond registering the type in a plugin init function. Once that is
done, the type is stored in the registry, and ready as soon as the
registry is loaded.

== Registering a type for dynamic loading
