        Another feature to create truly ugly TreeViews!: style properties
        for the even/odd colors used for row hinting. (#71595, reported
        by Owen Taylor).

        * gtk/gtktreeview.c (gtk_tree_view_class_init): add even_row_color
        and odd_row_color style properties.

        * gtk/gtkstyle.c (get_darkened_gc): support darken_count == 0 case,
        (gtk_default_draw_flat_box): rework cell coloring code to support
        user-provided even/odd row colors.

        Cache signal IDs to speed up signal emission. This is a good speedup
        because GtkTreeModel emits a big number of signals.

        * gtk/gtktreemodel.c (gtk_tree_model_base_init): save IDs returned
        by g_signal_new,
        (gtk_tree_model_row_changed): use g_signal_emit instead of
        g_signal_emit_by_name,
        (gtk_tree_model_row_inserted): ditto,
        (gtk_tree_model_row_has_child_toggled): ditto,
        (gtk_tree_model_row_deleted): ditto,
        (gtk_tree_model_rows_reordered): ditto.

        * gtk/gtktreeselection.c (model_changed): new function,
        (gtk_tree_selection_selected_foreach): monitor changes in the model,
        bail out if the model has been changed from the foreach func.
        (#50263, reported by Havoc Pennington).

        * gtk/gtktreeselection.c (_gtk_tree_selection_internal_select_node):
        free anchor if applicable (#94868, reported and testcase provided by
        Daniel Elstner).
