*
* A quality metric defined using 2D and 3D target metrics,
* where the active (A) matrix compared to the target by
* the underlying metrics is the Jacobian matrix of the
* mapping function at a given sample point. For surface
* elements, A is rotated to align the normal with W, such that
* both matrices can be reduced from 3x2 to 2x2.
