fn slerp_to_unnormalized(

    to: Vec3<f32>,
    factor: f32
) -> Result<Vec3<f32>, Vec3<f32>>

Begone ye NaN’s Slerp two Vec3s skipping the slerp if their directions are very close This avoids a case where veks slerp produces NaN’s Additionally, it avoids unnecessary calculations if they are near identical Assumes from is normalized and returns a normalized vector, but to doesn’t need to be normalized Returns Err(from)`` if to` is unnormalizable
