Anvils in item frames render incorrectly (as if it were deeper into frame) when viewed from below. From the side or above they appear correctly.

Recreate: place item frame, place anvil in frame, view from below.

Expected result: the black/grey of the anvil should not be interrupted by the frame's brown background (as side view).

Actual: frame background seems to be in front of parts of the anvil.

Another case of this: http://www.minecraftforum.net/topic/1533766-fence-texturing-broken/#entry18750733
