Post-processing

Note：We updated the post process document since v3.8 which can be found here Full-Screen Post Process.

To create a new post-processing effect, create a new RenderFlow script and set its type to POSTPROCESS. The production process is the same as other RenderFlow, but RenderPipeline does not automatically perform post-processing, it is necessary to set the flows property in the Camera to specify which post-processing to perform.
