Where to ask about gnomecanvas? (How to get all items via gnome_canvas_get_item_at?)

Hi,

is this the right place to ask a question about gnomecanvas?

I am using gnomecanvas for a mapping application (an openstreetmap editor for
maemo). Sometimes items are stacked (e.g. a building is a polygon which may
be placed in some some park which also is a polygon). The problem is that i need
to get access to all things located on a position, but gnome_canvas_get_item_at
only gives me only the top item. 

How do i get access to all items? The building in the example above may e.g. be 
drawn prior to the park and thus not be the topmost item and thus basically not
accessible. I could of course re-order the items, but my program basically has no
knowledge about buildings and the like. Everything is just a polygon (or a closed
way in openstreetmap). So i wouldn't know which thing to order in which way.
