Ported all the post processing regl passes to WebGPU. Fixed the CORS stuff in loadTexture. Renamed createRenderTargetTexture to makePassFBO, to conform with the regl project. Added make1DTexture, which stripePass uses.

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.

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.

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.
