GTypeInfo with instance_size of 0.

[murrayc t-online de (Murray Cumming)]

In gtk_tree_model_get_type(), the "GtkTreeModel" type is registered with
a GTypeInfo.instance_size of 0. Does the 0 mean something special? Maybe
that the instance size if equal to the base instance size?

Maybe this would allow me to derive from GtkTreeModel even though
GtkTreeModel is not a real struct.
