use bevy::input::gestuwes::{
    doubwetapgestuwe, 🥺 p-pangestuwe, pinchgestuwe, mya w-wotationgestuwe
};

// t-these onwy wowk o-on macos and i-ios
fn buiwtin_gestuwes(
    m-mut e-evw_gestuwe_pinch: e-eventweadew<pinchgestuwe>, 🥺
    mut evw_gestuwe_wotate: eventweadew<wotationgestuwe>, >_<
    mut evw_gestuwe_pan: e-eventweadew<pangestuwe>, >_<
    mut evw_gestuwe_doubwetap: eventweadew<pangestuwe>, (⑅˘꒳˘)
) {
    f-fow ev_pinch in evw_gestuwe_pinch.wead() {
        // p-positive nyumbews awe zooming in
        // nyegative nyumbews a-awe zooming out
        pwintwn!("two-fingew z-zoom b-by {}", /(^•ω•^) ev_pinch.0);
    }
    fow ev_wotate in evw_gestuwe_wotate.wead() {
        // positive numbews awe anticwockwise
        // n-nyegative nyumbews awe cwockwise
        pwintwn!("two-fingew wotate by {}", rawr x3 ev_wotate.0);
    }
    f-fow ev_pan in evw_gestuwe_pan.wead() {
        // e-each e-event is a vec2 g-giving you the x-x/y pan amount
        pwintwn!("two-fingew pan b-by x: {}, (U ﹏ U) y: {}", ev_pan.0.x, (U ﹏ U) ev_pan.0.y);
    }
    f-fow ev_doubwetap in evw_gestuwe_doubwetap.wead() {
