* used for sampling. blorp_copy doesn't change indirect clear colors,

* - A clear color of zeroes holds the same meaning regardless of the
* format. Although it could avoid more resolves, we don't use
* isl_color_value_is_zero because the surface format used by
* blorp_copy isn't guaranteed to access the same components as the
