TreeModelFilter.clearCache

This function should almost never be called. It clears the filter of any cached iterators that haven't been reffed with gtk_tree_model_ref_node(). This might be useful if the child model being filtered is static (and doesn't change often) and there has been a lot of unreffed access to nodes. As a side effect of this function, all unreffed iters will be invalid. Since 2.4
