export const description = `
Writes a single texel to a texture.
The channel format T depends on the storage texel format F.
See the texel format table for the mapping of texel format to channel format.
Note: An out-of-bounds access occurs if:
* any element of coords is outside the range [0, textureDimensions(t)) for the corresponding element, or
* array_index is outside the range of [0, textureNumLayers(t))
If an out-of-bounds access occurs, the built-in function may do any of the following:
* not be executed
* store value to some in bounds texel
