Red2D is a GPU accelerated 2D framework.  It was designed to make it easy to use Stage3D capabilities.  The framework has a complete set of features supporting cameras, filters, particles, texts and materials.

package basicAPIEx
{
    import red2D.Red_Scene;
    import red2D.display.Red_Sprite;
    import red2D.material.ColorMaterial;
    import red2D.text.Red_TextField;

    public class Test01_helloRed2D extends Red_Scene
    {

        private var _testRedSprite:Red_Sprite;
        private var _testText:Red_TextField;

        public function Test01_helloRed2D($bgColor:int=0)
        {
            super($bgColor);
        }

        public override function setDesign():void{

            _testRedSprite = new Red_Sprite(
                new ColorMaterial,
                {
                    x:0.5*stage.stageWidth,
                    y:0.5*stage.stageHeight
                }
            )

            addChild(_testRedSprite)

            _testText = new Red_TextField("Hello Red2DPlus",{size:30})
            _testText.textColor=0xffffff
            _testText.x = stage.stageWidth/2
            _testText.y = _testRedSprite.y+100
            addChild(_testText)
        }

        public override function update():void{
            _testRedSprite.rotation++
        }
    }
