    Class mat3

    A 3x3 matrix type supporting common linear algebra operations.

        const identity = new mat3();
        console.log('mat3 identity column0:', identity.column0.x, identity.column0.y, identity.column0.z);
        console.log('mat3 identity column1:', identity.column1.x, identity.column1.y, identity.column1.z);
        console.log('mat3 identity column2:', identity.column2.x, identity.column2.y, identity.column2.z);

        const custom = new mat3();
        custom.column0 = new vec3(1, 0, 0);
        custom.column1 = new vec3(0, 2, 0);
        custom.column2 = new vec3(0, 0, 3);
        console.log('Scaled mat3 diagonal:', custom.column0.x, custom.column1.y, custom.column2.z);
