I believe the light vector interpolation will result in "crooked" light
paths over the skin when your pose includes twist. I could be wrong, though,
which would be great. Or it may not be that noticeable.

You'll also have to be careful about interpolating across areas where
there's a lot of directional change between two vertices, as we're not
slerping quaternions here... Basically, I think fixing it up in the model to
force tesselation is the best solution here.
