CommandBuffer的相关内容参考如下，其用于扩展Build-in的管线，（LWRP中是否好用呢？）
https://docs.unity3d.com/Manual/GraphicsCommandBuffers.html
总结几点：
public void OnWillRenderObject() 中创建 CommandBuffer
buf.Blit (BuiltinRenderTextureType.CurrentActive, screenCopyID);获取当前Buffer中的颜色信息
其与GrabTexture原理是一样的。只不过后者在一些平台上支持不是很好。
模糊的代码如下：
// Upgrade NOTE: replaced 'mul(UNITY_MATRIX_MVP,*)' with 'UnityObjectToClipPos(*)'
Shader "Hidden/SeparableGlassBlur" {

_MainTex ("Base (RGB)", 2D) = "" {}
}

LWRP中引入了新的方式，但以下两个Texture，在ShaderGraph中
对应以下两个结点，如下所示，通过屏幕坐标，做为UV对SceneColor进行采样，并进行简单的抖动
效果如下：
Shader的代码，我们可以看到，以下代码是开启了Opaque功能
// Defines generated by graph
#define REQUIRE_OPAQUE_TEXTURE
简单总结一下Shader Graph的生成的代码
由三个Pass组成StandardUnlit ShadowCaster DepthOnly 后两者根据名字也能知道其使用了。与标准管线基本一致。
获取物体的Clip后坐标为o.position = TransformObjectToHClip(v.vertex.xyz);
