=for apidoc
Not like the original C function, which call as
goo_canvas_item_get_child_properties(item, child, key1, &val1, key2,
&val2, ..., NULL). This function call as
$item->get_child_properties($child, $key1, $key2, ...) and return a list
($key1, $val1, $key2, $val2, ...) instead. So you can call like
%pair = $item->get_child_properties($child, $key1, $key2) and use $pair{$key1} and $pair{$key2} to access the value for the property.
