// (WireTextureReadback.inc, ReadTextureImageWire): a colour level of exactly that extent is
// treated as a level the driver refused to attach, which is what an Adreno does for every one of
// these formats and what llvmpipe can be made to do no other way. The `DirectGLES.<arm>.StoreRead.`
// treated as a level the driver refused to attach - what a driver without EXT_texture_norm16 /
// EXT_render_snorm does for these formats (an Adreno 750, which has both, reads them all back

// entries set it, and this scenario then builds its textures at THAT extent instead of the default
// one - so the knob is scoped by the extent, and the tcp lane's shared supervisor can carry it
