Pausing a game by stopping Pixi's tickers

The code to pause the game is as following:

PIXI.ticker.shared.speed = 0;
ct.pixiApp.ticker.speed = 0;

And, to unpause:

PIXI.ticker.shared.speed = 1;
ct.pixiApp.ticker.speed = 1;

But it should be documented as a quick tip/tutorial in the docs, because one will never guess on how to do that, even with Pixi.js docs.

From Discord server:

If you are using ct.delta all over your game code, a simple line [...] must effectively disable motion of everything that uses that ct.delta. Default movement system with this.speed and this.direction is included here as well. At this point, the game loop will still work, meaning that UI and stuff will be responsible.
To set ct.delta back to normal, run [...].
So you need to:

1. Spawn a pause menu;
2. Set both tickers to 0;
3. Set them back to 1 when a player presses the "unpause" button
