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();
    	}
    }
