* expected, the GtkTreeIterCompareFunc must define a partial order on
* the model, i.e. it must be reflexive, antisymmetric and transitive.
*
* For example, if @model is a product catalogue, then a compare function
* for the “price” column could be one which returns
* `price_of(@a) - price_of(@b)`.
*
* Returns: a negative integer, zero or a positive integer depending on whether
