- * To check if the pointer coordinates are valid (e.g. a touch display
- * actually being touched), PRESSED returns 1 or 0.
- *
- * If using a mouse on a desktop, PRESSED will usually correspond to the
- * left mouse button, but this is a frontend decision.
- * PRESSED will only return 1 if the pointer is inside the game screen.
- *
- * For multi-touch, the index variable can be used to successively query

- * with _X, _Y for index = 0. One can then query _PRESSED, _X, _Y with
