I have to correct myself. The gtkadjustemts _do_ relate directly to the
scroll offset. This might be what the initial post in this thread was asking for.
This:

 GtkAdjustment *hadj = ((struct _GooCanvas*)map->canvas)->hadjustment;
 GtkAdjustment *vadj = ((struct _GooCanvas*)map->canvas)->vadjustment;
 gdouble hs, vs;
 hs = gtk_adjustment_get_value(hadj);
 vs = gtk_adjustment_get_value(vadj);
 goo_canvas_convert_from_pixels(GOO_CANVAS(map->canvas), &hs, &vs);

seems to return the current scroll position in hs and vs.

Even better, for a Python-working solution, you can create your own GtkAdjustments and call gtk.Widget.set_scroll_adjustments, then use
goocanvas.Canvas.convert_from_pixels.

Thanks for the help, all.
