Given a transform structure T, transform coordinates UV in the input space into coordinates XY in the output space.
Input and output coordinates may be given/retrieved either as a n-by-2 array, or as two n-by-1 vectors.
The function makes use of the "forward_fcn" field of the transform structure T, which should thus be defined.
