Actually the ping-pong setup isn't necessary for this compute shader, since it does everything in-place.
...
Undid all the y-flips I could find, and they all canceled one another out, except for the glyph UVs in the fragment shader.

We have ping-pong! And all the rain pass's shaders can coexist in one module! And I met and received ample help from @kainino0x and others on the WebGPU Matrix chat!

The MSDF stuff shouldn't be in its own uniform buffer. This is basically config stuff.

Consolidating all the bind groups, because I only have four. Stuff shared between render passes will get isolated somehow, but it might be by binding one buffer to multiple render passes' bind group at zero rather than having more than one bind group.

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.

Overhauled the rainPass's support for the "operator" version of the effect. It now overrides the brightness of any glyph brighter than a threshold, which I think is a much clearer concept.

Also changed the way the glyphs cycle in the "operator" version, after noticing they only change once every four or five frames in the original effect.
