I have a patch locally that fixed this within blorp, but I think I actually want to just change the driver interface so that Mesa core drives multi-slice copyteximages and the driver just gets a layer field for which one it's supposed to do. So I'm fine with this patch for the moment, since it will take a couple of days to do the core change. Reviewed-by: Eric Anholt <e...@anholt.net>
