    Sets a view transform matrix that moves and orients camera to look at a target point.

    This is useful for changing camera position and orientation. The resulting Mat4 matrix can be
    passed to `lovr.graphics.transform()` directly (without inverting) before rendering the scene.

    The lookAt() function produces same result as target() after matrix inversion.
