A syncWith method for Pixelmask.

[haydn]

I've added a method to Pixelmask that makes it easy to sync it with an instance of Image. For example in an entity you might have this:

public function MyEntity()
{
    var image:Image = new Image(IMAGE);

    image.originX = -200;
    image.angle = 45;

    graphic = image;
    mask = new Pixelmask(image);
}

That will automatically create a pixel mask with the same bounds and matching data to the image.

If the image is constantly updating the Pixelmask can be updated with it. Just use the syncWith method:

override public function update():void
{
    super.update();

    (graphic as Image).angle += 5;
    (mask as Pixelmask).syncWith(graphic as Image);
}

Why not just use Image objects for collisions instead of masks? I mean, youcan do a lot of transformations much easily.
