/** An action which can be triggered by a menu or toolbar item.
 *
 * Actions represent operations that the user can perform, along with
 * some information about how it should be presented in the user interface.
 * Each action provides methods to create icons, menu items and toolbar
 * items representing itself.
 *
 * As well as the callback that is called when the action is activated,
 * the following is also associated with the action:
 *
 *  - a name (not translated, for path lookup)
 *  - a label (translated, for display)
 *  - an accelerator
 *  - whether the label indicates a stock id
 *  - a tooltip (optional, translated)
 *  - a toolbar label (optional, shorter than label)
 *
 * The action will also have some state information:
 *
 *  - visible (shown/hidden)
 *  - sensitive (enabled/disabled)
 *
 * Apart from regular actions, there are toggle actions,
 * which can be toggled between two states and radio actions,
 * of which only one in a group can be in the "active" state.
 * Other actions can be implemented as Gtk::Action subclasses.
 *
 * Each action can have one or more proxy menu item, toolbar button or other proxy widgets.
 * Proxies mirror the state of the action (text label, tooltip, icon, visible, sensitive, etc), and should change when the action's state changes. When the proxy is activated, it should activate its action.
