When hitting a mob, the mob becomes lighter for short

Confirmed

Since MC-47941 was closed as a dup of a dup of this, please note that Creepers also flash White during their explosion animation. It used to be that he'd flash by only brightening his texture a bit. It looks like maybe a white mask is being applied with the incorrect (lost) transparency.

Still present in 14w07a.

Still present in 14w10b.

Not sure if it helps at all, but this was introduced in one of the 1.8 snapshots.

Confirmed for 14w08a and 14w10c, surely intended.

I don't think the creeper flashing white is intended, since it's untextured white, not just the light flashing it had before. It looks very weird.

Definitely not intentional.

Doesn't effect endermen and witches.
Confirmed for 14w11b.

Confirmed mob lighting fixed in 14w17a.
Creepers still flash a bright white, but it seems more translucent than it was before. Still not quite the same old creepers that was had in 1.7.
