Murray Cumming ac7b0c91ae ToolPalette: Implement GtkOrientable. 
* gtk/gtktoolpalette.[h|c]: Remove gtk_tool_palette_get/set_property(),
implementing GtkOrientable instead.
* gtk/gtktoolitemgroup.c:
* demos/gtk-demo/toolpalette.c: Use gtk_orientable_* instead.

* @short_description: A tool palette with categories
* @include: gtktoolpalette.h
*
* An #GtkToolPalette allows it to add #GtkToolItem<!-- -->s to a palette like container
* with different categories and drag and drop support.
*
* An #GtkToolPalette is created with a call to gtk_tool_palette_new().
*
* #GtkToolItem<!-- -->s cannot be added directly to an #GtkToolPalette, instead they
* are added to an #GtkToolItemGroup which can than be added to an #GtkToolPalette. To add
* an #GtkToolItemGroup to an #GtkToolPalette use gtk_container_add().
*
* |[
* GtkWidget *palette, *group;
* GtkToolItem *item;
*
* palette = gtk_tool_palette_new ();
* group = gtk_tool_item_group_new (_("Test Category"));
* gtk_container_add (GTK_CONTAINER (palette), group);
*
* item = gtk_tool_button_new_from_stock (GTK_STOCK_OK);
* gtk_tool_item_group_insert (GTK_TOOL_ITEM_GROUP (group), item, -1);
* ]|
*
* The easiest way to use drag and drop with GtkToolPalette is to call gtk_tool_palette_add_drag_dest()
* with the desired drag source @palette and the desired drag target @widget. Than gtk_tool_palette_get_drag_item()
* can be used to get the dragged item in the #GtkWidget::drag-data-received signal handler of the drag target.
