 When reading or sampling a depth channel via a `texture_depth_*`-typed binding, the value is
 returned as an `f32` value.

 As this was not a portability pain point for WebGL, it's not expected to be problematic in WebGPU.
 In practice, expect either `vec4<u32>(S, S, S, S)` or `vec4<u32>(S, 0, 0, 1)`, depending on hardware.
