How to use

class ofApp {
	ofxMacTrackpadTouchArg touches;
public:
	void receiveTouches(ofxMacTrackpadTouchArg &arg) {
		touches = arg;
	}
	
	void setup() {
		ofAddListener(ofxMacTrackpad::multitouch, this, &ofApp::receiveTouches);
		
		ofxMacTrackpad::startListen();
	}
	
	void draw() {
		for(auto &finger : touches.fingers) {
			ofDrawCircle(
				ofMap(finger.position.x, 0.0f, 1.0f, 0.0f, ofGetWidth()),
				ofMap(finger.position.y, 0.0f, 1.0f, 0.0f, ofGetHeight()),
				40
			);
		}
	}
};
