No wonder this felt familiar.

    mesa: only copy the requested teximage faces

    Cube maps are special in that they have separate teximages for each
    face. We handled that by copying the data to them separately, but in
    case zoffset != 0 or depth != 6 we would read off the end of the client
    array or modify the wrong images.

    zoffset/depth have already been verified by the time the code gets to
    this stage, so no need to double-check.

But I only applied it to regular tex images, not to compressed ones.
