Shield Model on Player is upside down.

I was trying to edit the texture for the shield to add a banner image to the front of it. I opened the texture in an image editor and applied the texture right side up. When i loaded the resource pack the texture appeared upside down. This is caused by the model for the shield on the player being rotated 180 degress. Although you cant tell because the shield front image is mirrored upside down and right side up. I had to flip the banner texture upside down to get it to show right side up. (Pictures included)
