/// minimal example of adding a custom render pipeline in bevy 0.11.
///
/// When this example runs, you should only see a blue screen. There are no
/// vertex buffers, or anything else in this example.  Effectively it is
/// shader-toy written in bevy.
///
/// This revision adds a post-processing node to the RenderGraph to
/// execute the shader.  Thanks to @Jasmine on the bevy discord for
/// suggesting I take a second look at the bevy post-processing example
