Tray structure defines an icon and a menu. A tray is defined by an icon, an optional tooltip and a menu.

* `int tray_init(struct tray *)` - creates tray icon. Returns -1 if tray icon/menu can't be created. * `int tray_init(struct tray *)` - creates the tray icon and its menu. Returns `-1` if the tray icon or menu cannot be created.
* `void tray_update(struct tray *)` - updates tray icon and menu. * `void tray_update(struct tray *)` - updates the tray icon, tooltip and menu state.
* `int tray_loop(int blocking)` - runs one iteration of the UI loop. Returns -1 if `tray_exit()` has been called. * `int tray_loop(int blocking)` - runs one iteration of the UI loop. Returns `-1` after `tray_exit()` has been called.
* `void tray_exit()` - terminates UI loop. * `void tray_exit(void)` - terminates the UI loop and cleans up tray resources.

Menu arrays must be terminated with a NULL item, e.g. the last item in the Menu arrays must be terminated with a NULL item, i.e. the last item in the
array must have text field set to NULL. array must have `text == NULL`.
### Notes
* `tooltip` is optional.
* A separator is created by using `text = "-"`.
* Some behavior may depend on the underlying backend or desktop environment.
Keep the public API generic and treat platform-specific interaction details as
backend-specific implementation behavior.
