Returns the default interface vtable for the given g_type.
If the type is not currently in use, then the default vtable
for the type will be created and initialized by calling
the base interface init and default vtable init functions for
the type (the base_init and class_init members of GObject.TypeInfo).
If you don't want to create the interface vtable, you should use
g_type_default_interface_peek() instead.
Calling g_type_default_interface_get() is useful when you
want to make sure that signals and properties for an interface
have been installed.
