General: Particles automatically removed depending on scale ?

    I had the problem that particles in a DisplayObjectRenderer were automatically removed at the global x position of 1024. I ran different tests and found out that the auto-removement depends on the particle's scale value.
    if I add an Scale Initializer with a value < 1 the particle is removed before 1024, if the value is > 1 its removed later. Really strange is that its calculated via tha global position. When I move the renderer to the right it still removes the particle at the same position.

    Can I somehow change this behavior? Is there a rule?

    Thanks!

    Here my test code:

    import org.flintparticles.common.counters.*;
    import org.flintparticles.common.displayObjects.RadialDot;
    import org.flintparticles.common.initializers.*;
    import org.flintparticles.twoD.actions.*;
    import org.flintparticles.twoD.emitters.Emitter2D;
    import org.flintparticles.twoD.initializers.*;
    import org.flintparticles.twoD.renderers.*;
    import org.flintparticles.twoD.zones.*;
    import flash.display.StageScaleMode;
    import flash.display.StageAlign;

    var emitter:Emitter2D = new Emitter2D();

    emitter.counter = new Steady( 50 );
    stage.align = StageAlign.TOP_LEFT
    stage.scaleMode = StageScaleMode.NO_SCALE

    emitter.addInitializer( new ImageClass( RadialDot, 2 ) );
    emitter.addInitializer( new Velocity( new PointZone( new Point(165, 0 ) ) ) );
    emitter.addInitializer( new ScaleImageInit( 0.5 ) ); // forces the particle to be removed at 512 px

    emitter.addAction( new Move() );

    var renderer:DisplayObjectRenderer = new DisplayObjectRenderer();
    renderer.addEmitter( emitter );

    renderer.y = 200
    addChild( renderer );

    emitter.start();

    I was able to reproduce the error, using your code as supplied. However, when I change the display object to something else, like the Dot or Star, the problem goes away. It seems to be an issue specifically with the radial dot. I can't find the cause and wonder if it's a display error in the Flash Player.
