Glow effect outline on mobs draws incorrectly

The Glow effect on some mobs (the outline drawn when mobs are hit by spectral arrows) draws incorrectly). See screenshots

All mobs: Outline does not draw around item in hands.

Slimes: Only draws the outline around he inner cubes. (Magma cubes draw correctly though)

Sheep: Like the slimes, the outline is around the body under the wool

Zombies: There is a gap near the head

Skeletons: Gap near head, around arms, and "holes" between ribs are not drawn

Chicken: outline around legs has a huge gap

Bats: Outline is offset with wings

Silverfish: Outline does not conform to pixels

Zombie pigman: Gap in areas where there is no hat layer.

Endermen: They teleport away when the arrow comes close. However, they still get the glow effect as if they were hit.
