I need to distinguish between what type of source made an InputEventScreenTouch. I need know if a finger, an stylus or a whole palm touched the UI. This is for an program running on an Android tablet.

I tested on with InputEvent.get_device(), and there is no distinction (everything returns 1).

On Android apps you can use the radius of contact with the screen to judge if it was a stylus (low radius) or a finger (higher radius). Can you get this information in Godot?
