//! Pause menu, from `rusting recipe apply pause_menu`.
//!
//! The action `menu` (Escape or the gamepad Start button) pauses the game
//! and its sounds and shows the HUD objects in `MENU`; pressing it again,
//! or clicking `Pause Resume`, carries on. `Pause Quit` closes the game.
//! Wire it up with `mod pause_menu;` in `src/main.rs` and
//! `pause_menu::pause_menu(scene);` in `update`.
