/**
* Rotates the array matrix based on the given rotation value.
*
* The value can be given in degrees: 90, -90, 270, -270 or 180,
* or a string command: `rotateLeft`, `rotateRight` or `rotate180`.
*
* Based on the routine from {@link http://jsfiddle.net/MrPolywhirl/NH42z/}.
*
* A matrix is a two-dimensional array (array of arrays), where all sub-arrays (rows)
* have the same length. There must be at least two rows. This is an example matrix:
*
* ```
* [
* [ 1, 1, 1, 1, 1, 1 ],
* [ 2, 0, 0, 0, 0, 4 ],
* [ 2, 0, 1, 2, 0, 4 ],
* [ 2, 0, 3, 4, 0, 4 ],
* [ 2, 0, 0, 0, 0, 4 ],
* [ 3, 3, 3, 3, 3, 3 ]
* ]
* ```
*
* @function Phaser.Utils.Array.Matrix.RotateMatrix
* @since 3.0.0
*
* @generic T
* @genericUse {T[][]} - [matrix,$return]
*
* @param {T[][]} [matrix] - The array to rotate.
* @param {(number|string)} [direction=90] - The amount to rotate the matrix by.
*
* @return {T[][]} The rotated matrix array. The source matrix should be discard for the returned matrix.
