Interface: FxShaderSpec

One effect's shader: its uniforms, and the body of its fragment function in GLSL (WebGL 2) and WGSL (WebGPU).

Both bodies are given the same helpers, so they read alike:

frameUv (vec2): 0–1 across the filtered area, whatever the size of the texture Pixi hands over;
framePx (vec2): the filtered area's size in pixels; texel (vec2): one input pixel in texture coordinates;
sampleAt(coord): the input at a texture coordinate, clamped inside the area; toCoord(uv): frame uv back to one;
coord: this fragment's texture coordinate; src: the input there (premultiplied alpha);
uMap / sampleMap(coord) when the effect has a second texture (map: true). GLSL reads its uniforms by name; WGSL through fx.<name>. Each body ends by writing result.
