Is it possible to output multiple textures in just one shader program?  
I read layout qualifier but don’t know how to apply it in GPUComputationRenderer.  
I wanna do like this if it is possible…

MRT was implemented just recently (by adding [WebGLMultipleRenderTargets](https://threejs.org/docs/index.html?q=multi#api/en/renderers/WebGLMultipleRenderTargets)) but `GPUComputationRenderer` does not support it yet.
