Calls the RenderPipelineManager.beginFrameRendering delegate.
This method is replaced by RenderPipeline.BeginContextRendering. It is supported and documented for backwards compatibility only.
If you are writing a custom Scriptable Render Pipeline, you can call this method at the start of your RenderPipeline.Render method to implement functionality using the RenderPipelineManager.beginFrameRendering delegate.
Using [RenderPipelineManager.beginFrameRendering]] causes heap allocations. Using RenderPipeline.BeginContextRendering and the RenderPipelineManager.beginContextRendering delegate provide the same functionality, but without heap allocations. You should therefore use RenderPipeline.BeginContextRendering and the RenderPipelineManager.beginContextRendering delegate instead.
