Function gilrs::ev::filter::axis_dpad_to_button

pub fn axis_dpad_to_button(
    ev: Option<Event>,
    gilrs: &mut Gilrs,
) -> Option<Event>

Maps axis dpad events to button dpad events.

This filter will do nothing if gamepad has dpad buttons (to prevent double events for same element) and if standard NativeEvCode for dpads is used by some other buttons. It will always try to map if SDL mappings contains mappings for all four hats.
