Félix Lescaudey de Maneville c4fc5d88f0 Fixed bevy_ui touch input (#4099) ... # Objective `bevy_ui` doesn't support correctly touch inputs because of two problems in the focus system: - It attempts to retrieve touch input with a specific `0` id - It doesn't retrieve touch positions and bases its focus solely on mouse position, absent from mobile devices ## Solution I added a few methods to the `Touches` resource, allowing to check if **any** touch input was pressed, released or cancelled and to retrieve the *position* of the first pressed touch input and adapted the focus system. I added a test button to the *iOS* example and it works correclty on emulator. I did not test on a real touch device as: - Android is not working (https://github.com/bevyengine/bevy/issues/3249) - I don't have an iOS device		2022-06-20 20:32:19 +00:00
