 Generates the [Wigner quasipropability distribution](https://en.wikipedia.org/wiki/Wigner_quasiprobability_distribution) of `state` at points `xvec + 1im * yvec` in phase space. The `g` parameter is a scaling factor related to the value of ``\hbar`` in the commutation relation ``[x, y] = i \hbar`` via ``\hbar=2/g^2`` giving the default value ``\hbar=1``.
