Deferred shading 2.5d isometric renderer.

This is the stand alone renderer part of game engine. All objects are 2d quads with preRendered normal and depth maps. No batching right now.

---

Starling 1.8 is used as a base 2d renderer. At least STANDARD profile must to be set up (MRT needed).

Render engine in motion: here

Strongly based on StarlingRendererPlus

Note3: There are 2 changes in starling RenderSupport class:

1.in assembleAgal function, version of agal is changed from defoult 1 to 2

        public static function assembleAgal(vertexShader:String, fragmentShader:String,
                                        resultProgram:Program3D=null):Program3D
    {
        if (resultProgram == null) 
        {
            var context:Context3D = Starling.context;
            if (context == null) throw new MissingContextError();
            resultProgram = context.createProgram();
        }
        
        resultProgram.upload(
            sAssembler.assemble(Context3DProgramType.VERTEX, vertexShader,2), //changed by Firebat version of agal from 1 to 2
            sAssembler.assemble(Context3DProgramType.FRAGMENT, fragmentShader,2));
        
        return resultProgram;
    }

2. There is added function renderTargets:

	public function setRenderTargets(targets:Vector.<Texture>, antiAliasing:int=0, enableDepthAndStencil:Boolean=true):void 
	{
		renderTarget = targets[0];
		mRenderTargets = targets;
		applyClipRect();
		
		var le:int = mRenderTargets.length;
		var context:Context3D = Starling.context;
		
		for(var i:int = 0; i < le; i++)
		{
			// All render targets with colorOutputIndex > 0 must be reset to null before switching to backbuffer
			// New render target could be a texture again and not backbuffer, but we should still reset it
			
			if(i != 0 || targets[i] != null)
			{
				//trace(targets[i] +"<--------multi");
				context.setRenderToTexture(targets[i] ? targets[i].base : null, enableDepthAndStencil, antiAliasing, 0, i);
			}
		}
		
		if(!renderTarget)
		{
			//trace("To back buffer");
			context.setRenderToBackBuffer();
		}
	}
