i see, though i have to say that all these
func (GtkZView    *zview,
      GtkZViewNode node);
arguments look a bit strange (like the programmer forgot to add that
asterisk). if a model uses an offset, it'll have to cast ala
GPOINTER_TO_UINT (node) anyways, right? so we could still use

typedef struct _GtkZNode GtkZNode;
func (GtkZView     *zview,
      GtkZViewNode *node);

without changing things significantly in the non-struct model implementations.
