This structure is used to provide the type system with the information
required to initialize and destruct (finalize) a type\'s class and
its instances.

The initialized structure is passed to the 'GI.GObject.Functions.typeRegisterStatic' function
(or is copied into the provided 'GI.GObject.Structs.TypeInfo.TypeInfo' structure in the
'GI.GObject.Interfaces.TypePlugin.typePluginCompleteTypeInfo'). The type system will perform a deep
copy of this structure, so its memory does not need to be persistent
across invocation of 'GI.GObject.Functions.typeRegisterStatic'.
