As described in the comment, enabling the round_to_nearest_even results in the upper 2^-9 of the texel i being sampled at i+1. This appears to be allowed by the spec, but triggers a CTS bug[1]. Changing this behavior is not necessary (we could fix the CTS), but is desirable regardless because of the precision improvement.
