Cannot achieve anti-aliasing to work

[Seymur]

I am trying to create a basic game in the Heaps. When I run it, I see Anti Aliasing not working. This is the screenshot and my sample code.

import h3d.Engine;

class Main extends hxd.App {
	var bmp:h2d.Bitmap;

	override function init() {
		Engine.ANTIALIASING = 4;
		var default_font = hxd.res.DefaultFont.get();
		default_font.resizeTo(24);
		var tf = new h2d.Text(default_font, s2d);
		tf.text = "Hello World !";

		var tile = h2d.Tile.fromColor(0xFF0000, 100, 100);
		bmp = new h2d.Bitmap(tile, s2d);

		bmp.x = s2d.width * 0.5;
		bmp.y = s2d.height * 0.5;
	}

	override function update(dt:Float) {
		super.update(dt);

		bmp.rotation += 0.1 * dt;
	}

	static function main() {
		new Main();
	}
}
