Mask offset error in case of scaling

Hi, Mask offset error in case of scaling.

Code:

import h2d.Graphics;
import h2d.Mask;
import hxd.App;

class Main extends App {
	static function main() {
		new Main();
	}

	override function init() {
		super.init();
		// All right
		var bg = new Graphics(this.s2d);
		bg.beginFill(0x0000ff);
		bg.drawRect(0, 0, 200, 200);
		bg.endFill();
		var mask = new Mask(200, 200, this.s2d);
		var g = new Graphics(mask);
		g.beginFill(0xff0000);
		g.drawRect(0, 0, 200, 200);
		g.endFill();
		mask.scrollX = 100;

		// Bug
		var bg = new Graphics(this.s2d);
		bg.beginFill(0x0000ff);
		bg.drawRect(0, 0, 200, 200);
		bg.endFill();
		var mask = new Mask(200, 200, this.s2d);
		var g = new Graphics(mask);
		g.beginFill(0xff0000);
		g.drawRect(0, 0, 200, 200);
		g.endFill();
		mask.scrollX = 100;
		mask.scaleX = 0.8;
		mask.scaleY = 0.8;
		mask.y = 300;
        bg.scale(mask.scaleX);
        bg.y = mask.y;
	}
}
