/**
 * This is a helper function to resolve an issue with opposite quaternions being interpolated by
 * OpenGL. 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, W2) < 0. In that case, you can flip either of them, therefore
 * making Dot(-Q1, W2) positive.
 *
 * NOTE: This solution corrects this issue per-vertex before passing the quaternions to OpenGL. This
 * should be correct for nearly all cases, however a more correct implementation (but less trivial
 * and perhaps unnecessary) would be to handle this per-fragment, by interpolating the quaternions
 * manually using two Lerps, and doing this correction before each Lerp.
