Normalise gltf quaternions #62

Closed Rennzie closed 2 years ago

Normalise Node rotation quaternions per the GlTF spec.

We noticed some converted files where invalid when run against the gltf-Validator. The error message:

"code": "ROTATION_NON_UNIT", "message": "Rotation quaternion must be normalized." Added a normalise function similar to gl-matrix which solves the problem.

Apologies again. After more investigation, it's clear the issue is not forge-convert-utils but rather the GLB writer we've used.
