Wither's rib cage is not in the center of its model

That's really hard to unsee.

It's actually that the center head is offcenter, the rest of the model is correct.

The heads are lined up perfectly with the center of its hitbox.

It seems the main reason the spine and ribcage are offcenter is because the spine’s front and back faces are 3 pixels wide (odd), while the wither’s main head is 8 pixels wide (even). So it has to be off center in order to aline with the pixel grid.

I see two possible solutions to this:

1. Adjust the spine’s model and texture to be an even number of pixels wide on the front and back faces.

2. Adjust the main head’s model and texture to be an odd number of pixels wide on the front and back faces.

If one of these solutions is done, the main head, spine, and ribcage will be centered.
