- * @class 2x3 Matrix

- * @description 
- * A mat2d contains six elements defined as:
- * <pre>
- * [a, b,
- *  c, d,
- *  tx,ty]
- * </pre>
- * This is a short form for the 3x3 matrix:
- * <pre>
- * [a, b, 0
- *  c, d, 0
- *  tx,ty,1]
- * </pre>
- * The last column is ignored so the array is shorter and operations are faster.
