-/**
- * This is a helper function to resolve an issue when interpolating opposite quaternions. See below
- * for a detailed description of this issue (yuriks):
- *
- * For any rotation, there are two quaternions Q, and -Q, that represent the same rotation. If you
- * interpolate two quaternions that are opposite, instead of going from one rotation to another
- * using the shortest path, you'll go around the longest path. You can test if two quaternions are
- * opposite by checking if Dot(Q1, Q2) < 0. In that case, you can flip either of them, therefore
- * making Dot(Q1, -Q2) positive.
- *
- * This solution corrects this issue per-vertex before passing the quaternions to OpenGL. This is
- * correct for most cases but can still rotate around the long way sometimes. An implementation
- * which did `lerp(lerp(Q1, Q2), Q3)` (with proper weighting), applying the dot product check
- * between each step would work for those cases at the cost of being more complex to implement.
- *
- * Fortunately however, the 3DS hardware happens to also use this exact same logic to work around
- * these issues, making this basic implementation actually more accurate to the hardware.
