Matrix4

class Matrix4(val m00: Float, val m01: Float, val m02: Float, val m03: Float, val m10: Float, val m11: Float, val m12: Float, val m13: Float, val m20: Float, val m21: Float, val m22: Float, val m23: Float, val m30: Float, val m31: Float, val m32: Float, val m33: Float)

Represents a 4x4 matrix.

The Matrix4 is implemented in row-major order and follows basic calculation principles:

Associativity: (m1 * m2) * m3 = m1 * (m2 * m3).
Distributivity: (m1 + m2) * m3 = (m1 * m3) + (m2 * m3).
