import javafx.application.Application;
import javafx.scene.Group;

    private static final double OPACITY_MODIFIER = 0.002;

    private double currentOpacity = START_OPACITY;
    private double strokeWidth = 15;

    public static void main(String[] args) {
        Application.launch(BrushTester.class);
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
