Texture mesh models are shaded incorrectly in fancy graphics mode

Steps to Reproduce:

1. Set graphics mode to Fancy

2. Grab a bow

3. Enter third person view

4. Look around

Observed Results:
The “outer” side of the bow is always dark, and the “inner” side is always bright.

Expected Results:
The brightness of the outer and inner sides roughly match the shading of your arm.

Screenshots/Videos attached: Yes

Notes: The shading only ignores rotations applied to the texture mesh elements in the model definition. Rotations applied through bone animations are properly accounted for.
