Class MutableMatrix22

A mutable 2x2 matrix class that extends Matrix22 and provides modification capabilities. This class allows in-place operations for matrix transformations, making it suitable for performance-critical applications where object creation overhead should be minimized.

The matrix is stored in column-major order as a Float32Array, compatible with WebGL. Matrix layout:

| m00 m01 |
| m10 m11 |

Example

const matrix = MutableMatrix22.identity();
matrix.rotate(Math.PI / 4); // Rotate 45 degrees
matrix.scale(Vector2.fromCopyArray([2, 3])); // Scale by 2x and 3y
