/**
 * A matrix in javascript notation is a 4x4 array of numbers.
 * This means that the matrix is represented as follows:
 *
 * | 0  1  2  3 |
 * | 4  5  6  7 |
 * | 8  9 10 11 |
 * | 12 13 14 15|
 *
 * which is row-major order. (unlike column-major order in mathematical notation).
 *
 * Since the individual components in mathematical notation look like this:
 *
 * | sx  0  0 tx |
 * |  0 sy  0 ty |
 * |  0  0 sz tz |
 * |  0  0  0  1 |
 *
 * we need to transpose the indices to get the correct values.
 *
 * | sx  0  0  0 |
 * |  0 sy  0  0 |
 * |  0  0 sz  0 |
 * | tx ty tz  1 |
 *
