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.

Merged the vertex and fragment shader WGSL files, because their bindings can't collide anyhow. The rain render shader now accepts a bind group of time uniforms, which change on every frame, as well as MSDF uniforms, along with an MSDF sampler and texture that's loaded in from the PNG. The shader currently renders the correct grid of quads for volumetric mode, displays the first glyph raw in each one, and every sixty frames, turns on and off the blue channel.
