I disagree: the formulas take care of that automatically provided that you parametrise your surface (or curve, or manifold) correctly.

Hence my earlier remark that A needs to be a rectangle. So if the range of integration in your "natural" corrdinate space is not a rectangle then you have got your parametrisation wrong and need to fix that first before doing the integration.

You might want to introduce a separate function for transforming the differentials between one parametrisation and another, but I thnk the Prime already has an implementation of the required Jacobian that can be used...
