My friend recommended a much simpler blur that doesn't build any image pyramids. Unfortunately my work towards an implementation isn't very promising— it doesn't pack the same wollop as the WebGL version— but I can built my pyramids on top of it.

Just learned about the private storage class. The rain pass can use it to look up the corner positions of quads, rather than derive them mathematically.

The WebGPU rainPass now performs a high pass filter on its own fragments. I think I prefer this to a separate high pass filter, because this one is pre-blendfunc, ie. fragments will only be added to the texture if they are individually bright enough to contribute.

The webgpu project's multi-pass pipeline is borrowed from the regl project, but the outputs don't exist yet. Outputs will be tricky, because RTTs are thrown out and recreated when the canvas resizes, which I think means all the bind groups referencing the old texture have to be destroyed and recreated, too.
