There are new symbols now, that can be used to represent path integrals. We should test those symbols in production and make people aware that constructs like

<math>\iint_{\partial V}\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\;\;\;\subset\!\supset \vec D\;\cdot\mathrm{d}\vec A = \iiint_{V} \rho \ \mathrm{d}V = Q(V)</math>

are no longer required.
