/**
* Reverses the row order of the given Array Matrix, which has the effect of reversing
* the sequence of values within each column from top to bottom.
*
* 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.ReverseColumns
* @since 3.0.0
*
* @generic T
* @genericUse {T[][]} - [matrix,$return]
*
* @param {T[][]} [matrix] - The array matrix whose row order will be reversed.
*
* @return {T[][]} The column reversed matrix.
